RTP1

RTP1 is the first television channel of Rádio e Televisão de Portugal, the Portuguese public broadcasting corporation. The first television channel launched in Portugal, RTP1 was launched in 1957 as RTP (and today it is still sometimes marketed as such), and also having a brief period while it was known and marketed as Canal 1 (Channel 1) (although it is still commonly treated by such name). It is one of the most watched television networks in the country. The channel became a 24-hour service in 2002, although it now leases its graveyard slot (3am to 6am) to the infomercial producer and direct-response marketer, A Loja Em Casa (in turn owned by El Corte Inglés).

RTP1 has a variety of programs, composed mainly of news and talk-shows, sports, current affairs, national and international fiction, such as films and TV series. Unlike sister channel RTP2, RTP1 broadcasts commercial advertising, which, along with government grants, finances the channel.
