Forget traditional video-on-demand and voice over DSL —sports-on-demand is the killer broadband app everyone has been searching for, according to Mark Kersey, an ARS broadband and cable analyst.

Sports-on-demand, or SOD as he affectionately calls it, enables sports fans to purchase individual games or a season package to watch games of their favorite team(s). "The accessibility factor of Internet-based SOD is by far its greatest asset and is in stark contrast to Internet-based VOD sites offering streams of popular movies such as 'A Beautiful Mind' that can easily be rented from the local video store," says Kersey.
