Comcast's plans to do away with its 250 GB data cap and charge users based upon usage marks the end of an era for cable TV providers, and for the online video industry. No longer will users be able to endlessly stream all the content their hearts desire. Not just that, but the fact that usage-based pricing is arriving at the same time that more, higher-quality content is appearing online could have a dampening effect on demand for services like Netflix or Hulu Plus. Comcast, of course, says that its new, usage-based pricing policy is pro-consumer, and to a certain extent it is.
