Diema Vision was founded at 15 may 1999 by Emil Slavchev, Anatoli Belchev and Asen Radulov. The first owned channel was Diema +. Over the years the channel proves popular and the company launches a second channel - Diema 2. At the end of 2005 it was sold to Apace Media, owned by Kamen Vodenicharov. In March 2007 Diema Vision became part of Balkan Media Group Limited, a joint venture between Apace Media Group UK and the international entertainment-broadcasting group Modern Times Group MTG AB and rebrands the main channel only as Diema, dropping the "plus" from it's name. In March 2009, MTG announced an agreement that would see the assets of Balkan Media Group Limited merge with the newly acquired Nova television. On 12 September 2011 the channel changed its look and logo again alongside the other Nova TV channels.
