IDC estimates that the IPTV market in Western Europe is currently worth around $500 mln, and will grow at a CAGR of 71% to reach $4.3 bln by 2010. In the next five years, household penetration of IPTV services will increase from 1% in 2006 to 11% by 2010. The countries that will make up a large portion of this growth are France, Italy, and Spain, where the pay-TV markets are less developed than elsewhere in Western Europe, where the first large IPTV services were launched, and where some of the more innovative providers are based.
