An increasing number of TV viewers worldwide will get their service from ISPs rather than cable or satellite providers, according to eMarketer analysis. Although still a fraction of the global market for TV, the number of people who subscribe to television over Internet Protocol (IPTV) will grow to 75 million through 2015. IPTV offers marketers great long-tail targeting possibilities, as customer-selected custom channel lineups promise highly-interested viewers. IPTV also holds interactivity possibilities beyond what is available via traditional cable-delivered TV.
