Radio Brunei was launched on 2 May 1957, and officially opened on 28 May. At the time, Radio Brunei broadcast for 45 minutes each evening, from 20:00 until 20:45 BST. The range of the single 1.2Kw transmitter was only five miles, which covered the capital and some surrounding areas.
As of 1974, RTB had increased its staff to 171 employees, and had a total of three transmitting sites. This gave near total coverage of the country and beyond.
Televisyen Brunei was officially launched on 1 February 1975 as Channel 5 and Channel 8.
On 1 March 1976, two high-power medium-wave stations in the Brunei-Muara District began transmission, expanding the coverage of radio and television services to almost 100% of the country.
