MTV Sub (formerly TVTV!, Subtv and Sub) is a Finnish television channel owned by MTV Oy. The previous owner Alma Media sold Sub and its sister channels (MTV3, C More Max, MTV Ava Radio Nova and Sävelradio) to Swedish Bonnier and Proventus in 2005.
Sub is an entertainment channel directed at teens and young adults. Programs are mostly imported and of U.S. origin. Sub also shows reruns of popular and cult TV shows. Recently, the share of domestic programming has grown remarkably.
The channel's highest viewership of all time was attracted in 2009, when the finale of Big Brother 2009 was aired.
Subteksti was Sub's teletext service. It contained music news, TV schedules and interactive services like chats and mobile phone games and services.
