Yle TV1 is a Finnish television channel owned and operated by Finnish public broadcaster Yle. It is the first and oldest television channel in Finland. More than 70% of channel's programs are documentaries, news or educational programs. Its name is commonly referred to as Ykkönen; the name is derived from Yle's ownership of channel spots 1 and 2 by default in Finland.
The channel started test transmissions on 13 August 1957 and began regular broadcasts on 1 January 1958 as Suomen Television. When Yleisradio took over Tampere-based Tamvisio in 1964, Suomen Television was renamed TV-ohjelma 1 and Tamvisio became TV-ohjelma 2 – and when they started broadcasting in color in the 1970s, they were rebranded again, as TV1 and TV2.
