Verizon first started experimenting with streaming live TV channels to tablets a couple of years ago, and had announced plans to make most of the channels on their FiOS system available to customers. Then copyright and licensing got in the way. Verizon argued that the multichannel licenses they held and subscribers paid for entitled them to watch the channels regardless of whether it was delivered to a TV set through a set-top box or to a tablet through WiFi. The cable networks argued that since the licenses were made before WiFi streaming was viable, it did not include that delivery method, and they wanted extra cash to extend license coverage to streaming options.
However, all that only works when the subscribers have paid for a video bundle that includes the channel, subscribes to FiOS Internet service, and uses a Verizon-supplied WiFi router. In addition, the live program streaming to iPads only works over WiFi in the subscriber's home. Finally, at least for now, it does not include local stations feed or major broadcast networks.
Not quite "TV Everywhere", but it's a welcome start.
