Cable and satellite may have been the early advocates of Video on Demand (VOD), but according to a new NPD report, AT&T (NYSE: T) U-verse and Verizon (NYSE: VZ) FiOS customers are spending the most money on the service. In 2012, U-verse and FiOS subscribers spent an average of $25.29 on VOD. Although AT&T and Verizon combined held an 18 percent share of the transactional VOD market in 2012, NPD said the "telcos are growing at a faster rate than other multichannel providers." Meanwhile, Comcast's (Nasdaq: CMCSA) and Time Warner Cable's (NYSE: TWC) shares of the VOD business dropped 28 percent and 10 percent in 2012, respectively. Article
