MOSCOW — The prexy of Russia’s leading entertainment television network, CTC, is to step down from Aug. 1 after seven years, the company said Wednesday.

Alexander Rodnyansky — who joined CTC Media in 2002 after successfully establishing television companies in Ukraine that included Kiev’s Studio 1+1 — served as CEO of CTC between 2004 and August last year.

Rodnyansky, who will continue to serve as a board member, is one of Russia’s top movie producers, whose two-part “Inhabited Island” — based on a Soviet sci-fi novel — was released this year. With a budget of nearly $40 million, it is the country’s most expensive movie ever.

Rodnyansky also co-owns Russia’s national Kinotavr film festival, which runs early June in the Black Sea resort of Sochi.

CTC Media runs CTC, DTV and Domashny channels in Russia, owns two TV content production companies, Costafilm and Soho Media, and operates Channel 31 in Kazakhstan and TV companies in Uzbekistan and Moldova.
