Summary.... Free video-on-demand (VoD) transmissions of movies on US cable have been a huge hit with consumers, with Comcast alone generating 3.6bn free VoD views last year. While free VoD has certainly proved a valuable weapon in cable's battle with satellite and IPTV, it has meant content owners have seen little revenue from VoD. Major studio revenues from all types of paid VoD were only $743m in 2008 - and AMR expects this to grow to $2bn by 2013.
