All five – FilmBox, FilmBox Arthouse, FightBox HD, Fast&FunBox HD and DocuBox HD – have both Russian and English language feeds.
SPI has also widened its reach elsewhere in the Baltic region.
In Latvia, Media Centrs Kurzeme now carries FightBox HD and Fast&Fun Box HD, while Electrons&K offers FightBox HD and DocuBox HD.
Meanwhile, in Lithuania the cable operator UAB Splius recently added FightBox HD to its thematic package.
Commenting on the development, Berk Uziyel, executive director at SPI International / Filmbox, said: “We are excited to see our distribution footprint expand across the Baltic countries. Our channels offer top quality entertainment and we are certain TV viewers in the region will enjoy them as we continue signing more distribution deals with local operators”.
