RTB Perdana (formerly known as RTB1 and Television Brunei, stylised as RTB perdana)[1] is the oldest free-to-air terrestrial television channel in Brunei. The channel officially began broadcasting on 1 March 1975.
RTB Perdana broadcasts for 05:40 until 23:20 BST followed by a prayer in Makkah filling the rest of its broadcasting time. It mainly shows documentaries, educational programs and news during its broadcasting time.
Brunei was first scheduled to have long-term plans for a television service as far back as 1964, when a representant of the Marconi Company had visited Brunei early that year, carried a geographic survey and sent a report to the government.[2] The 1965 report made by Canadian firm Pappas and Associates claimed that there were no technical issues, and the final decision was up to the Sultan, who had seen television in trips abroad. Ground work for the new service would cost $3 million, $10 million for the final total. The main issue was the lack of technical staff to sustain the service. The Sultan believed to have mentioned the issue in what was at the time his latest trip to the UK.[3]
These plans were later delayed to 1969, towards the end of the first lapse of time given during the first study regarding the feasibility of a television service. If introduced, the service would be used for "religious, cultural, educational and entertainment purposes". A commercial service was out of the cards.[4] The plan was aborted on 31 March 1968, in order to cut the Bruneian expenditure. Among the reasons given were the lack of producing local programming.[5]
When RTM started broadcasting a special service for East Malaysia, by conducting test transmissions in the state of Sabah, in February 1971, Bruneians claimed to have picked up the Malaysian signals, but some viewers questioned if it was a hoax.[6] Once the test transmissions were over, shops started selling television sets under the counter under the risk of having problems with the authorities. A "TV fever" had begun.[7] When Brunei was about to witness a five-year economic boom, there was the possibility of launching a television service.[8] By 1973, 3,000 television sets existed in Brunei.[9]
Yusof Ahmad, a former Malay programmes editor at RTS, was granted a job at RTB for the then-upcoming colour television service.[10]
The first phase of the pilot service launched on 10 July 1975, costing B$30 million. BBC and RTS executives assisted in its launch. RTB's television service was initially receivable only in Bandar Seri Begawan. A second transmitter to cover the rest of the protectorate was to be included in a second phase.[11]
On 11 April 2017, RTB1 along with sister station RTB5 officially merged and renamed RTB Perdana as part of RTB's rebranding project as well as broadcaster's shift from analogue into digital broadcasting.[1]
