Bangladesh Betar, or BB is the state-owned radio broadcaster of Bangladesh, initially established as the Dhaka station of All India Radio in 1939. It was later made part of Radio Pakistan. After the independence of the country in 1971, Radio Pakistan ceased transmissions there and the Swadhin Bangla Betar Kendra was renamed to Bangladesh Betar, which took full control of all radio stations in the country at the time.

Shahbagh is a major neighbourhood and a police precinct or thana in Dhaka, the capital and largest city of Bangladesh. It is also a major public transport hub. It is a junction between two contrasting sections of the city—Old Dhaka and New Dhaka—which lie, respectively, to its south and north. Developed in the 17th century during Mughal rule in Bengal, when Old Dhaka was the provincial capital and a centre of the flourishing muslin industry, it came to neglect and decay in early 19th century. In the mid-19th century, the Shahbagh area was developed as New Dhaka became a provincial centre of the British Raj, ending a century of decline brought on by the passing of Mughal rule.
