How successful will IPTV be?

Jeff Halpern  from Bernstein Research has estimated that 5.5 million people will subscribe to IPTV by 2010. Although this may seem like a high number, Berstein Research has actually lowered its estimations. It had previously projected that IPTV subscriptions would reach the lofty number of 5.5 million by 2009, an entire year earlier than now estimated. Halpurn attributes the lowering in subscription projections to "slower franchise approval process, greater technological challenges and slower deployment into residential MDUs than originally forecast," according to the article Analyst: 5.5 Million Telco Video Subs in 2010.
