IDC predicts that the US market for bundled services will grow from fewer than 45 mln customer relationships today to more than 84 mln in 2010. Today, many US households are already receiving cable and Internet services from the same provider (double play). In a few years, these customers will be subscribing to additional services from that provider (triple or quadruple play) for the benefit of one less bill to pay. By mid-2008, IDC forecasts a significant shift from double-play broadband and video to triple-play broadband, video, and voice. This trend signals a significant shrinking of standalone services within each core industry such as voice and cable. However, when voice and cable are bundled with other services, the outlook is much brighter.
