In-theater ads hit $456 million in 2006, up 15% from 2005, says the Post, citing a report by the Cinema Advertising Council. For perspective, this is about the size of Viacom’s “digital” revenue. The head of the council, Cliff Marks, who also happens to be head of sales for the public play in the sector, National Cine-Media (NCMI, see below), says that the introduction of digital projectors is helping spur adoption, as advertisers no longer have to burn ads onto film.
