In 1978, Minas Gerais' TV Alterosa became one of the SBT's broadcast-affiliate networks, the first affiliate station for the channel. Some later affiliates were adopted from Rede Tupi after its closure on 18 July 1980, by order of Brazilian Minister of Communications Haroldo de Matos, who the following year would order SBT to begin transmissions. When Tupi closed, "Programa Silvio Santos" moved to Record but continued simulcasting Sundays on the TVS Channels 11 and 3, as well as on yet another SS Group station - Channel 9, purchased from TV Continental. Santos began the network's expansion efforts, convincing stations to become the SBT and Record affiliates. The official launch of the network on 19 August 1981, also marked the debut of its first presentation package using its famous circle logo (similar to the one used till today by the American Broadcasting Company) and dual branding (the SBT being the official name of the network while TVS being the station branding in its three founding stations), and it was the only network launch to be held in Brasilia and broadcast directly from the federal capital city. The first idents were similar to ABC's "Still the One" idents of 1979, used by the Nine Network in Australia in 1980.
