as Muzik FM. Most Radio 3 Local service radio stations adopted names based on place names in Malay language followed by FM. Sabah's non-Malay language service was rebranded as Sabah V FM, while Sarawak's English and Chinese language and Bumiputera language services were rebranded as Red FM and Wai FM respectively. Radio 4 English language service was rebranded as Traxx FM. Radio 5 Chinese language service was rebranded as Ai FM. Radio 6 Tamil language service was rebranded as Minnal FM. Radio 7 Aslian language service was rebranded as Asyik FM. Original Malay Melody Radio service was rebranded as Klasik FM. On 12 August 2006, Nasional FM merged with Klasik FM to form Klasik Nasional FM, and broadcast classical Malay music together with its main program 24 hours a day. However, the merger survived for only five years, as the station began losing listeners to sister stations and private competitors such as Hot FM, Sinar FM and Era FM, as well as then-upstart Bernama's Radio24 which took over the frequencies of Klasik FM. Thus, Klasik Nasional was demerged on 4 January 2012 at midnight and split into the original two radio stations, with Nasional FM using the same frequencies as the former Muzik FM (discontinued in late 2012) and Klasik Nasional became Radio Klasik. Owing to the diminished effectiveness of a shortwave radio service over time with changing technology and media consumption habits, Voice of Malaysia was dissolved on 31 August 2011. TV1 broadcast overnight many times since the early 1990s, but daily 24-hour transmissions did not come until 2003, which was later cancelled. Permanent 24-hour broadcasting was introduced on 3 April 2006 on TV2 and on 21 August 2012 on TV1. Three new TV channels were launched during the digital television broadcasting era: TV Okey on 21 March 2018, News channel Berita RTM on 25 June 2020 and Sports channel Sukan RTM on 1 April 2021. TV Pendidikan returned to RTM on 6 April 2020 and began to air on TV Okey.
