RTP1

Background
RTP (Rádio e Televisão de Portugal) was established in December 1955 with test broadcasts conducted in September 1956 at the now-defunct Feira Popular amusement park in Lisbon. It was the only TV channel available in Portugal until December 25, 1968, when RTP2 started broadcasting. Because of that, RTP had to identify both channels as I Programa and II Programa in order to distinguish them. Towards the end of the 1980s, RTP was facing challenges with the impending arrival of private broadcasters. As a result, RTP decided to rename RTP1 as RTP Canal 1, in readiness for a bigger rebrand that happened on September 17, 1990, where the channel was now officially rebranded as Canal 1, in order to reinforce its position in front of the new broadcasters. On April 29, 1996, Canal 1 reverted to RTP1.
