National Exhibition Centre
The National Exhibition Centre is an exhibition centre located in Solihull, England. It is near junction 6 of the M42 motorway, is adjacent to Birmingham Airport and Birmingham International railway station, it has 20 interconnected halls, set in grounds of 611 acres making it the largest exhibition centre in the UK. It is the busiest and seventh-largest exhibition centre in Europe. Opened by Elizabeth II in February 1976, the first event to be staged at the venue was International Spring Fair, which has returned every year since. Growing annually, the event now occupies all of the Resorts World Arena; the NEC was going to be built adjacent to the M1 motorway near Leicester but it was turned down by Leicestershire County Council with claims that "The big shows won't move away from London."In November 1971, the Secretary of State for the Environment granted outline planning approval for the National Exhibition Centre in Birmingham. On 16 February 1973 Prime Minister Edward Heath travelled up from London to cut a white ribbon and initiate its construction.
The NEC comprising 89,000 m2 of exhibition space, was opened by the Queen on 2 February 1976. The building was designed by Edward Mills; the seventh hall of the NEC complex, a multi-purpose indoor arena, opened in December 1980 as Birmingham International Arena. On 23 March 1989, the Queen opened three further halls, increasing the space to 125,000 m2. Four more halls were added in 1993, the total exhibition space increasing to 158,000 m2. Another four new halls, opened in September 1998 by Neil Kinnock European Commissioner for Transport, took the total space to 190,000 m2; these buildings were designed by Seymour Harris. The NEC is nearing completion of a five-year, £40 million venue improvement programme which has seen improvements made to everything from the car parking to signage and catering; the most obvious result of this development has been the redesign of the Piazza – the central space around Halls 1 to 5, which has received a contemporary update. The NEC was home to the British International Motor Show from 1978 to 2004.
It hosts the Classic Motor Show. Since 1991, the NEC has been the venue for the international dog show Crufts. Held over four days and using five halls as well as the Genting Arena, Crufts attracts an estimated 160,000 visitors annually; the 1991 show was Crufts centenary year and as part of the celebrations to mark the occasion, the Guinness Book of Records gave official recognition of the event's status as the world's largest dog show, with 22,973 dogs being exhibited that year. The NEC was the venue for the Iron Maiden live album Maiden England.

In May 2013, The National Exhibition Centre announced it would be hosting a series of corporate Christmas parties for the first time. The parties run from 8 to 21 December 2013, it was the venue for Great Britain's Davis Cup match against Holland in 2007. The Resorts World Arena is part of the complex; the NEC has 29,000 car parking spaces spread around the site, with a shuttle bus service operating to and from the car parks. From 1 April 2015 the all-day parking fee for public exhibitions is £12.00, which contributes directly to the upkeep of the car parks, running of the shuttle bus service, maintenance of road surfaces and lighting and manning of the areas with traffic stewards. Parent company The NEC Group owns and operates the Arena Birmingham and ICC Birmingham, both in central Birmingham, the Resorts World Arena, based on The NEC site. In October 2018, Blackstone acquired NEC Group from Lloyds Development Capital, the private equity unit of Lloyds Banking Group. Official website The NEC Birmingham Business event calendar
The British Broadcasting Corporation is a British public service broadcaster. Its headquarters are at Broadcasting House in Westminster, it is the world's oldest national broadcasting organisation and the largest broadcaster in the world by number of employees, it employs over 20,950 staff in total. The total number of staff is 35,402 when part-time and fixed-contract staff are included; the BBC is established under a Royal Charter and operates under its Agreement with the Secretary of State for Digital, Culture and Sport. Its work is funded principally by an annual television licence fee, charged to all British households and organisations using any type of equipment to receive or record live television broadcasts and iPlayer catch-up; the fee is set by the British Government, agreed by Parliament, used to fund the BBC's radio, TV, online services covering the nations and regions of the UK. Since 1 April 2014, it has funded the BBC World Service, which broadcasts in 28 languages and provides comprehensive TV, online services in Arabic and Persian.
Around a quarter of BBC revenues come from its commercial arm BBC Studios Ltd, which sells BBC programmes and services internationally and distributes the BBC's international 24-hour English-language news services BBC World News, from BBC.com, provided by BBC Global News Ltd. From its inception, through the Second World War, to the 21st century, the BBC has played a prominent role in British culture, it is known colloquially as "The Beeb", "Auntie", or a combination of both. Britain's first live public broadcast from the Marconi factory in Chelmsford took place in June 1920, it was sponsored by the Daily Mail's Lord Northcliffe and featured the famous Australian soprano Dame Nellie Melba. The Melba broadcast caught the people's imagination and marked a turning point in the British public's attitude to radio. However, this public enthusiasm was not shared in official circles where such broadcasts were held to interfere with important military and civil communications. By late 1920, pressure from these quarters and uneasiness among the staff of the licensing authority, the General Post Office, was sufficient to lead to a ban on further Chelmsford broadcasts.
But by 1922, the GPO had received nearly 100 broadcast licence requests and moved to rescind its ban in the wake of a petition by 63 wireless societies with over 3,000 members. Anxious to avoid the same chaotic expansion experienced in the United States, the GPO proposed that it would issue a single broadcasting licence to a company jointly owned by a consortium of leading wireless receiver manufactures, to be known as the British Broadcasting Company Ltd. John Reith, a Scottish Calvinist, was appointed its General Manager in December 1922 a few weeks after the company made its first official broadcast; the company was to be financed by a royalty on the sale of BBC wireless receiving sets from approved domestic manufacturers. To this day, the BBC aims to follow the Reithian directive to "inform and entertain"; the financial arrangements soon proved inadequate. Set sales were disappointing as amateurs made their own receivers and listeners bought rival unlicensed sets. By mid-1923, discussions between the GPO and the BBC had become deadlocked and the Postmaster-General commissioned a review of broadcasting by the Sykes Committee.
The Committee recommended a short term reorganisation of licence fees with improved enforcement in order to address the BBC's immediate financial distress, an increased share of the licence revenue split between it and the GPO. This was to be followed by a simple 10 shillings licence fee with no royalty once the wireless manufactures protection expired; the BBC's broadcasting monopoly was made explicit for the duration of its current broadcast licence, as was the prohibition on advertising. The BBC was banned from presenting news bulletins before 19.00 and was required to source all news from external wire services. Mid-1925 found the future of broadcasting under further consideration, this time by the Crawford committee. By now, the BBC, under Reith's leadership, had forged a consensus favouring a continuation of the unified broadcasting service, but more money was still required to finance rapid expansion. Wireless manufacturers were anxious to exit the loss making consortium with Reith keen that the BBC be seen as a public service rather than a commercial enterprise.
The recommendations of the Crawford Committee were published in March the following year and were still under consideration by the GPO when the 1926 general strike broke out in May. The strike temporarily interrupted newspaper production, with restrictions on news bulletins waived, the BBC became the primary source of news for the duration of the crisis; the crisis placed the BBC in a delicate position. On one hand Reith was acutely aware that the Government might exercise its right to commandeer the BBC at any time as a mouthpiece of the Government if the BBC were to step out of line, but on the other he was anxious to maintain public trust by appearing to be acting independently; the Government was divided on how to handle the BBC but ended up trusting Reith, whose opposition to the strike mirrored the PM's own. Thus the BBC was granted sufficient leeway to pursue the Government's objectives in a manner of its own choosing; the resulting coverage of both striker and government viewpoints impressed millions of listeners who were unaware that the PM had broadcast to the nation from Reith's home, using one of Reith's sound bites inserted at the last moment
Birmingham is the second-most populous city in the United Kingdom, after London, the most populous city in the English Midlands. It is the most populous metropolitan district in the United Kingdom, with an estimated 1,137,123 inhabitants, is considered the social, cultural and commercial centre of the Midlands, it is the main local government of the West Midlands conurbation, the third most populated urban area in the United Kingdom, with a population of 2,897,303 in 2017. The wider Birmingham metropolitan area is the second largest in the United Kingdom with a population of over 4.3 million. It is referred to as the United Kingdom's "second city". A market town in the medieval period, Birmingham grew in the 18th-century Midlands Enlightenment and subsequent Industrial Revolution, which saw advances in science and economic development, producing a series of innovations that laid many of the foundations of modern industrial society. By 1791 it was being hailed as "the first manufacturing town in the world".
Birmingham's distinctive economic profile, with thousands of small workshops practising a wide variety of specialised and skilled trades, encouraged exceptional levels of creativity and innovation and provided an economic base for prosperity, to last into the final quarter of the 20th century. The Watt steam engine was invented in Birmingham; the resulting high level of social mobility fostered a culture of political radicalism which, under leaders from Thomas Attwood to Joseph Chamberlain, was to give it a political influence unparalleled in Britain outside London, a pivotal role in the development of British democracy. From the summer of 1940 to the spring of 1943, Birmingham was bombed by the German Luftwaffe in what is known as the Birmingham Blitz; the damage done to the city's infrastructure, in addition to a deliberate policy of demolition and new building by planners, led to extensive urban regeneration in subsequent decades. Birmingham's economy is now dominated by the service sector.
The city is a major international commercial centre, ranked as a beta- world city by the Globalization and World Cities Research Network. Its metropolitan economy is the second largest in the United Kingdom with a GDP of $121.1bn, its six universities make it the largest centre of higher education in the country outside London. Birmingham's major cultural institutions – the City of Birmingham Symphony Orchestra, the Birmingham Royal Ballet, the Birmingham Repertory Theatre, the Library of Birmingham and the Barber Institute of Fine Arts – enjoy international reputations, the city has vibrant and influential grassroots art, music and culinary scenes. Birmingham is the fourth-most. People from Birmingham are called Brummies, a term derived from the city's nickname of "Brum", which originates from the city's old name, which in turn is thought to have derived from "Bromwich-ham"; the Brummie accent and dialect are distinctive. Birmingham's early history is that of a marginal area; the main centres of population and wealth in the pre-industrial English Midlands lay in the fertile and accessible river valleys of the Trent, the Severn and the Avon.
The area of modern Birmingham lay in between, on the upland Birmingham Plateau and within the densely wooded and sparsely populated Forest of Arden. There is evidence of early human activity in the Birmingham area dating back to around 8000 BC, with stone age artefacts suggesting seasonal settlements, overnight hunting parties and woodland activities such as tree felling; the many burnt mounds that can still be seen around the city indicate that modern humans first intensively settled and cultivated the area during the bronze age, when a substantial but short-lived influx of population occurred between 1700 BC and 1000 BC caused by conflict or immigration in the surrounding area. During the 1st-century Roman conquest of Britain, the forested country of the Birmingham Plateau formed a barrier to the advancing Roman legions, who built the large Metchley Fort in the area of modern-day Edgbaston in AD 48, made it the focus of a network of Roman roads. Birmingham as a settlement dates from the Anglo-Saxon era.
The city's name comes from the Old English Beormingahām, meaning the home or settlement of the Beormingas – indicating that Birmingham was established in the 6th or early 7th century as the primary settlement of an Anglian tribal grouping and regio of that name. Despite this early importance, by the time of the Domesday Book of 1086 the manor of Birmingham was one of the poorest and least populated in Warwickshire, valued at only 20 shillings, with the area of the modern city divided between the counties of Warwickshire and Worcestershire; the development of Birmingham into a significant urban and commercial centre began in 1166, when the Lord of the Manor Peter de Bermingham obtained a charter to hold a market at his castle, followed this with the creation of a planned market town and seigneurial borough within his demesne or manorial estate, around the site that became the Bull Ring. This established Birmingham as the primary commercial centre for the Birmingham Plateau at a time when the area's economy was expanding with population growth nationally leading to the clearance and settlement of marginal land.
Within a century of the charter Birmingham had grown into a prosperous urban centre of merchants and craftsmen. By 1327 it was the third-largest town in Warwickshire, a position it would retain for the next 200 years; the principal governing institutions of medieval Birmingham – including the Guild of the Ho
The automotive industry is a wide range of companies and organizations involved in the design, manufacturing and selling of motor vehicles. It is one of the world's largest economic sectors by revenue; the automotive industry does not include industries dedicated to the maintenance of automobiles following delivery to the end-user, such as automobile repair shops and motor fuel filling stations. The word automotive is from the Greek autos, Latin motivus to refer to any form of self-powered vehicle; this term, as proposed by Elmer Sperry, first came into use with reference to automobiles in 1898. The automotive industry began in the 1860s with hundreds of manufacturers that pioneered the horseless carriage. For many decades, the United States led the world in total automobile production. In 1929, before the Great Depression, the world had 32,028,500 automobiles in use, the U. S. automobile industry produced over 90% of them. At that time the U. S. had one car per 4.87 persons. After World War II, the U.
S. produced about 75 percent of world's auto production. In 1980, the U. S. was overtaken by Japan and became world's leader again in 1994. In 2006, Japan narrowly passed the U. S. in production and held this rank until 2009, when China took the top spot with 13.8 million units. With 19.3 million units manufactured in 2012, China doubled the U. S. production, with 10.3 million units, while Japan was in third place with 9.9 million units. From 1970 over 1998 to 2012, the number of automobile models in the U. S. has grown exponentially. Safety is a state that implies to be protected from any risk, damage or cause of injury. In the automotive industry, safety means that users, operators or manufacturers do not face any risk or danger coming from the motor vehicle or its spare parts. Safety for the automobiles themselves, implies that there is no risk of damage. Safety in the automotive industry is important and therefore regulated. Automobiles and other motor vehicles have to comply with a certain number of norms and regulations, whether local or international, in order to be accepted on the market.
The standard ISO 26262, is considered as one of the best practice framework for achieving automotive functional safety. In case of safety issues, product defect or faulty procedure during the manufacturing of the motor vehicle, the maker can request to return either a batch or the entire production run; this procedure is called product recall. Product recalls happen in every industry and can be production-related or stem from the raw material. Product and operation tests and inspections at different stages of the value chain are made to avoid these product recalls by ensuring end-user security and safety and compliance with the automotive industry requirements. However, the automotive industry is still concerned about product recalls, which cause considerable financial consequences. Around the world, there were about 806 million cars and light trucks on the road in 2007, consuming over 980 billion litres of gasoline and diesel fuel yearly; the automobile is a primary mode of transportation for many developed economies.
The Detroit branch of Boston Consulting Group predicts that, by 2014, one-third of world demand will be in the four BRIC markets. Meanwhile, in the developed countries, the automotive industry has slowed down, it is expected that this trend will continue as the younger generations of people no longer want to own a car anymore, prefer other modes of transport. Other powerful automotive markets are Iran and Indonesia. Emerging auto markets buy more cars than established markets. According to a J. D. Power study, emerging markets accounted for 51 percent of the global light-vehicle sales in 2010; the study, performed in 2010 expected this trend to accelerate. However, more recent reports confirmed the opposite. In the United States, vehicle sales peaked in 2000, at 17.8 million units. The OICA counts over 50 countries which assemble, manufacture or disseminate automobiles. Of that figure, only 13, boldfaced in the list below, possess the capability to design automobiles from the ground up; this is a list of the 15 largest manufacturers by production in 2016.
It is common for automobile manufacturers to hold stakes in other automobile manufacturers. These ownerships can be explored under the detail for the individual companies. Notable current relationships include: Daimler AG holds a 10.0% stake in KAMAZ. Daimler AG holds an 89.29% stake in Mitsubishi Fuso Truck and Bus Corporation. Daimler AG holds a 3.1% in the Renault-Nissan Alliance. Daimler AG holds a 12% stake in Beijing Automotive Group, Daimler AG holds an 85% stake in Master Motors. Dongfeng Motor holds a 12.23% stake and a 19.94% exercisable voting rights in PSA Groupe. FAW Group owns 49% of Haima Automobile. FCA holds a 10% stake in Ferrari. FCA holds a 67% stake in Fiat Automobili Srbija. FCA holds 37.8% of Tofaş with another 37.8% owned by Koç Holding. Fiat Automobili Srbija owns a 54% stake in Zastava Trucks. Fiat Industrial owns a 46% stake in Zastava Trucks. Fujian Motors Group holds a 15% stake in King Long. FMG, Beijing Automotive Group, China Motor, Daimler has a joint venture called Fujian Benz.
FMG, China Motor, Mitsubishi Motors has a joint venture called Soueast, FMG holds a 50% stake, both China Motor and Mitsubishi Motors holds an equal 25% stake. Geely Automobile holds a 23% stake in The London Taxi Company. Geely Automobile holds a 49.9% stake in PROTON Holdings and a 51% stake in Lotus Cars. Geely Holding Group holds a 9.69% stake in Daimle
Entrepreneurship is the process of designing and running a new business, initially a small business. The people who create these businesses are called entrepreneurs. Entrepreneurship has been described as the "capacity and willingness to develop and manage a business venture along with any of its risks in order to make a profit". While definitions of entrepreneurship focus on the launching and running of businesses, due to the high risks involved in launching a start-up, a significant proportion of start-up businesses have to close due to "lack of funding, bad business decisions, an economic crisis, lack of market demand—or a combination of all of these. A broader definition of the term is sometimes used in the field of economics. In this usage, an Entrepreneur is an entity which has the ability to find and act upon opportunities to translate inventions or technology into new products: "The entrepreneur is able to recognize the commercial potential of the invention and organize the capital and other resources that turn an invention into a commercially viable innovation."
In this sense, the term "Entrepreneurship" captures innovative activities on the part of established firms, in addition to similar activities on the part of new businesses. Entrepreneurship is the act of being an entrepreneur, or "the owner or manager of a business enterprise who, by risk and initiative, attempts to make profits". Entrepreneurs oversee the launch and growth of an enterprise. Entrepreneurship is the process by which either an individual or a team identifies a business opportunity and acquires and deploys the necessary resources required for its exploitation. Early-19th-century French economist Jean-Baptiste Say provided a broad definition of entrepreneurship, saying that it "shifts economic resources out of an area of lower and into an area of higher productivity and greater yield". Entrepreneurs create something new, something different—they change or transmute values. Regardless of the firm size, big or small, they can partake in entrepreneurship opportunities; the opportunity to become an entrepreneur requires four criteria.
First, there must be situations to recombine resources to generate profit. Second, entrepreneurship requires differences between people, such as preferential access to certain individuals or the ability to recognize information about opportunities. Third, taking on risk is a necessity. Fourth, the entrepreneurial process requires the organization of resources; the entrepreneur is a factor in and the study of entrepreneurship reaches back to the work of Richard Cantillon and Adam Smith in the late 17th and early 18th centuries. However, entrepreneurship was ignored theoretically until the late 19th and early 20th centuries and empirically until a profound resurgence in business and economics since the late 1970s. In the 20th century, the understanding of entrepreneurship owes much to the work of economist Joseph Schumpeter in the 1930s and other Austrian economists such as Carl Menger, Ludwig von Mises and Friedrich von Hayek. According to Schumpeter, an entrepreneur is a person, willing and able to convert a new idea or invention into a successful innovation.
Entrepreneurship employs what Schumpeter called "the gale of creative destruction" to replace in whole or in part inferior innovations across markets and industries creating new products including new business models. In this way, creative destruction is responsible for the dynamism of industries and long-run economic growth; the supposition that entrepreneurship leads to economic growth is an interpretation of the residual in endogenous growth theory and as such is hotly debated in academic economics. An alternative description posited by Israel Kirzner suggests that the majority of innovations may be much more incremental improvements such as the replacement of paper with plastic in the making of drinking straws; the exploitation of entrepreneurial opportunities may include: Developing a business plan Hiring the human resources Acquiring financial and material resources Providing leadership Being responsible for both the venture's success or failure Risk aversionEconomist Joseph Schumpeter saw the role of the entrepreneur in the economy as "creative destruction" – launching innovations that destroy old industries while ushering in new industries and approaches.
For Schumpeter, the changes and "dynamic disequilibrium brought on by the innovating entrepreneur the norm of a healthy economy". While entrepreneurship is associated with new, for-profit start-ups, entrepreneurial behavior can be seen in small-, medium- and large-sized firms and established firms and in for-profit and not-for-profit organizations, including voluntary-sector groups, charitable organizations and government. Entrepreneurship may operate within an entrepreneurship ecosystem which includes: Government programs and services that promote entrepreneurship and support entrepreneurs and start-ups Non-governmental organizations such as small-business associations and organizations that offer advice and mentoring to entrepreneurs Small-business advocacy organizations that lobby governments for increased support for entrepreneurship programs and more small business-friendly laws and regulations Entrepreneurship resources and facilities Entrepreneurship education and training programs offered by schools and universities Financing In the 2000s, usage of the term "entrepreneurship" expanded to include how and why some individuals ide
An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages. They differ from chat rooms in that messages are longer than one line of text, are at least temporarily archived. Depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes publicly visible. Forums have a specific set of jargon associated with them. A discussion forum is hierarchical or tree-like in structure: a forum can contain a number of subforums, each of which may have several topics. Within a forum's topic, each new discussion started is called a thread and can be replied to by as many people as so wish. Depending on the forum's settings, users can be anonymous or have to register with the forum and subsequently log in to post messages. On most forums, users do not have to log in to read existing messages; the modern forum originated from bulletin boards, so-called computer conferencing systems, are a technological evolution of the dialup bulletin board system.
From a technological standpoint, forums or boards are web applications managing user-generated content. Early Internet forums could be described as a web version of an electronic mailing list or newsgroup. Developments emulated the different newsgroups or individual lists, providing more than one forum, dedicated to a particular topic. Internet forums are prevalent in several developed countries. Japan posts the most with over two million per day on 2channel. China has many millions of posts on forums such as Tianya Club; some of the first forum systems were the Planet-Forum system, developed at the beginning of the 1970-s, the EIES system, first operational in 1976, the KOM system, first operational in 1977. One of the first forum sites is Delphi Forums, once called Delphi; the service, with four million members, dates to 1983. Forums perform a function similar to that of dial-up bulletin board systems and Usenet networks that were first created starting in the late 1970s. Early web-based forums date back as far as 1994, with the WIT project from W3 Consortium and starting from this time, many alternatives were created.
A sense of virtual community develops around forums that have regular users. Technology, video games, music, fashion and politics are popular areas for forum themes, but there are forums for a huge number of topics. Internet slang and image macros popular across the Internet are abundant and used in Internet forums. Forum software packages are available on the Internet and are written in a variety of programming languages, such as PHP, Java and ASP; the configuration and records of posts can be stored in a database. Each package offers different features, from the most basic, providing text-only postings, to more advanced packages, offering multimedia support and formatting code. Many packages can be integrated into an existing website to allow visitors to post comments on articles. Several other web applications, such as blog software incorporate forum features. WordPress comments at the bottom of a blog post allow for a single-threaded discussion of any given blog post. Slashcode, on the other hand, is far more complicated, allowing threaded discussions and incorporating a robust moderation and meta-moderation system as well as many of the profile features available to forum users.
Some stand alone threads on forums have reached fame and notability such as the "I am lonely will anyone speak to me" thread on MovieCodec.com's forums, described as the "web's top hangout for lonely folk" by Wired Magazine. A forum consists of a tree-like directory structure; the top end is "Categories". A forum can be divided into categories for the relevant discussions. Under the categories are sub-forums and these sub-forums can further have more sub-forums; the topics come under the lowest level of sub-forums and these are the places under which members can start their discussions or posts. Logically forums are organized into a finite set of generic topics driven and updated by a group known as members, governed by a group known as moderators, it can have a graph structure. All message boards will use one of three possible display formats; each of the three basic message board display formats: Non-Threaded/Semi-Threaded/Fully Threaded, has its own advantages and disadvantages. If messages are not related to one another at all, a Non-Threaded format is best.
If a user has a message topic and multiple replies to that message topic, a semi-threaded format is best. If a user has a message topic and replies to that message topic and responds to replies a threaded format is best. Internally, Western-style forums logged in members into user groups. Privileges and rights are given based on these groups. A user of the forum can automatically be promoted to a more privileged user group based on criteria set by the administrator. A person viewing a closed thread as a member will see a box saying he does not have the right to submit messages there, but a moderator will see the same box granting him access to more than just posting messages. An unregistered user of the site is known as a guest or visitor. Guests are granted access to all functions that do not require database alterations or breach privacy. A guest can view the contents of the forum or use such features as read marking, but an administrator will disallow visi
