RTP1 is the main television channel of Rádio e Televisão de Portugal, the Portuguese public broadcasting corporation. Portugal's first channel, RTP1 was launched in 1957 as RTP. For a brief period it was known and marketed as Canal 1 (Channel 1); it is still commonly called this. 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 (4am to 6am) to the infomercial producer and direct-response marketer, A Loja Em Casa (in turn owned by El Corte Inglés). Up until that point, RTP1 closed down with the national anthem, but this practice stopped not too long before infomercials filled the overnight slots. 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 the licence fee, finances the channel. ==History== RTP was established in December 1955 with test broadcasts conducted in September 1956 at the now-defunct Feira Popular amusement park in Lisbon. Regular broadcasts commenced at 21:30 on March 7, 1957. Initially the channel broadcast from 21:30 to either 23:00 or 23:30, with an additional period on Sundays between 18:00 and 19:00. Initially, RTP had a very limited coverage area, encompassing the northern and central coastal areas of Portugal, before expanding to the whole of the mainland in the mid-1960s. On October 19, 1959, ''Telejornal'' went on air for the first time, becoming the longest-running Portuguese TV show in existence. 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. Daytime broadcasts commenced in 1970, with a two-hour period running at various times mostly between 12:30 and 14:30. Before then, Telescola (educational classes) were generally the first programmes of the day and the regular schedule started at 19:00, running until midnight. In 1974, RTP's ratings grew with the expansion of the acquisition of television sets in the country. The first color broadcasts were conducted in 1976, with the legislative elections. In 1978, the channel was renamed RTP-1 (initially hyphenated). Color programming was now in production, and a heat of Jeux Sans Frontières has to be transmitted in said technology in order to air to the rest of Europe, which already had regular color broadcasts at the time. As the months progressed, more and more color broadcasts were included before launching regularly on March 7, 1980. In October 1983, the daytime period was abolished in order to save energy. Weekday broadcasts were then restricted to start at 17:00 and end at 23:00. Said broadcasts were resumed in 1985, when RTP decided to broadcast the daytime block from Oporto. The educational broadcasts (then known as Ciclo Preparatório TV) were abolished in 1988. By then, daytime shutdowns were abolished. 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. Having lost its leadership status slowly between 1994 and 1995, owing to SIC's success, it eventually turned into the vice-leader before falling into third place, when TVI got a ratings boost. On April 29, 1996, Canal 1 reverted to RTP1. In 2002, Emílio Rangel joined RTP 1, coming from SIC, changing the face of public television in Portugal but causing havoc on the broadcaster. During this phase, the channel had overly-long news bulletins (i.e. Telejornal ending as late as 21:30) and thought-provoking debate shows (Gregos e Troianos). On March 31, 2004, RTP1 rebranded entirely now broadcasting from RTP's new headquarters. The channel started widescreen tests on June 8, 2012 with the Euro 2012 opening ceremony and the first match (Poland vs. Greece). On January 14, 2013, the channel formally became a widescreen channel. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RTP1」の詳細全文を読む スポンサード リンク
