customers are cutting back on cable bills: while rates go up every year, the average amount consumers are paying for digital cable dropped from $79 a month in the third quarter of 2008 to $70 in the third quarter of 2009 as they drop additional channels and services, according to research from Centris. Cable still has the most complete reserves of TV programming, films and video-on-demand, as well as a near-lock on live sports and news. But web-based devices are getting closer to offering the full deal. Avner Ronen, CEO of startup Boxee, estimates 60% of broadcast TV is available online free in some form, and 10% of cable TV.
