YLE TV1 is a Finnish television channel owned and operated by Finnish public broadcaster Yleisradio. It is the first and oldest Television channel in Finland. More than 70% of channel's programs are documentaries, news or educative programmes. Its name is commonly referred to as Ykkönen or Ylen Ykkönen; the name is derived from the fact that YLE owns channel spots 1 and 2 by default in Finland.
The channel started broadcasting on 1 January 1958 as Suomen Televisio. When Yleisradio took over Tampere-based Tamvisio in 1964, Suomen Televisio was renamed TV-ohjelma 1 and Tamvisio became TV-ohjelma 2 - and when they started broadcasting in colour in the 1970s, they were rebranded again, as TV1 and TV2.
