GBP was formed in 1982 as a video making company specialising in commercials for Belize's then-small television industry.
It had a hand in the creation of several 1980s and 1990s motion pictures, including "Dogs of War" (1980), "The Mosquito Coast" (1986), "Caribe" (1987) and "Heart of Darkness" (1993).
Great Belize Productions' first successful television series actually predates Channel 5.
Telemedia is rumored to still be majority-owned by Lord Michael Ashcroft, a fact which rankled many Belizeans.
Amandala columnist Frankie Rhys announced shortly after the sale that he would stop watching Channel 5 in protest; KREM's Evan Mose Hyde has since frequently called GBP's Channel 5 "Ashcroft TV" in protest of the sale.
