Corel Corporation is a Canadian software company headquartered in Ottawa, specializing in graphics processing. It is known for producing software titles such as CorelDRAW, for acquiring AfterShot Pro, PaintShop Pro, Video Studio and WordPerfect. Corel was founded by Michael Cowpland in 1985 as a research laboratory; the company had great success early in the high-tech boom of the 1990s and early 2000s with the product CorelDRAW, became, for a time, the biggest software company in Canada. In 1996 it acquired Novell WordPerfect and started competing with the thought of being "Pepsi to Microsoft's Coke" as Microsoft Word was the top-used word processing software at the time. Corel was in a difficult position as Microsoft pushed pre-loaded copies of its software onto new computers; this consisted of Microsoft Works office applications, but a variant called Works Suite bundled the Microsoft Word software. The company held the naming rights to the home arena for the NHL's Ottawa Senators from February 1996 until January 2006 as the "Corel Centre", a venue known as the Canadian Tire Centre.

In 1997 Corel sold its Corel ChemLab studio and its "CD Home Collection" consisting of over 60 multimedia titles to Hoffmann + Associates, a Toronto-based company. As part of the deal, Corel acquired a minority interest in Hoffmann + Associates and received royalties. In August 2000 Cowpland was left. A new board of directors was appointed and Derek Burney Jr. announced that the product line would be split into several brands—DeepWhite, ProCreate, Corel. However, these plans would be scrapped, only the Corel brand would remain. Corel acquired the graphics software company Micrografx in late 2001. In August 2003, Corel was bought out by the private equity firm Vector Capital for $1.05 a share. The company was voluntarily delisted from the Toronto Stock Exchanges; some U. S. shareholders alleged the management benefited from the buyout while the buyout price was too low. A lawsuit was filed in the U. S. to was unsuccessful. In March 2005 Corel announced that the United States Justice Department purchased 50,000 licenses of WordPerfect and that WordPerfect was adding 4 million new users per year thanks to bundling deals with Dell.

Corel contended that WordPerfect was the only viable alternative to Microsoft Office, with sales 70 times more than Lotus' SmartSuite. On April 26, 2006, Corel completed its return to the public market with an initial public offering on NASDAQ, the same day finalizing the acquisition of WinZip, a well-known archiving software title. On December 12, 2006, Corel completed its acquisitions of Ulead; the InterVideo acquisition was valued at around $196 million. In May 2008, CEO David Dobson announced that he was leaving the company to take a senior strategy role at Pitney Bowes. Dobson was replaced on May 8 by former Symantec executive Kris Hagerman. In November 2009, it was announced that Vector Capital would be purchasing the remaining shares of common stock in Corel Corporation. Upon completion, this made Corel once again owned. On January 29, 2010, the shareholders of Corel approved its announced stock consolidation, completing the transfer to Corel Holdings, L. P. a limited partnership controlled by an affiliate of Vector Capital.

In January 2012, Corel acquired Roxio from Rovi Corporation for an undisclosed amount. Subsequently on July 2, 2012, Corel announced its acquisition of Pinnacle Systems, a developer of consumer-oriented video editing products owned by Avid. Having suffered layoffs in 2003 and 2008, Corel began a near yearly culture of restructuring beginning in 2010, when in the latter part of that year the company's finance department was restructured and moved to their Taipei office, resulting in significant layoffs at its Ottawa HQ. Restructuring in 2012 resulted in more layoffs. In December 2013, the company's restructuring resulted in the layoffs of the Taipei locations engineering and quality assurance team. Corel's Taipei office was the core development centre of PaintShop Pro and VideoStudio, one of the company's most well-known photo- and video-editing bundles; the 2013 restructuring led to a partial handover of product development to outsourced companies, resulting in more rapid, low-cost development across its product lines.

The company continued with layoffs in 2014 and once again at the beginning of 2015 with the change of the company's CEO to Patrick Nichols the head of Corel's WinZip business unit. In August 2016, Corel announced the acquisition of the Mindjet MindManager business from Spigit. In June 2018, Corel announced the acquisition of Gravit GmbH. In December 2018, Corel announced the acquisition of Parallels. On July 3, 2019, Corel was sold to KKR.

Askaryan Radio Array

The Askaryan Radio Array is a new detector designed to detect a few GZK neutrinos a year. It measures the enhanced radio-frequency radiation emitted during the interaction of the neutrino in Antarctic ice sheet; the detection is based on the Askaryan effect, an idea by Gurgen Askaryan This detection technique is being used by the Antarctic Impulse Transient Antenna and the Radio Ice Cerenkov Experiment detectors. The ARA experiment will be built around the IceCube experiment, will cover an area of 100 square kilometers. A 16-antenna prototype station, the "ARA Testbed", of the ARA system was installed January 2011 and began operation allowing the ARA Collaboration to determine the estimated sensitivity of the array design: ARA-37 will cover 200 km2 with neutrino sensitivity of 1016–1019 eV. Measurements of the radio background and ice attenuation length were reported; the first ARA station was installed in the season 2011–2012. The ARA array had five stations as of 2018; the Phase 1 goal of ARA is 37 stations.
