4G just now getting fast enough to deliver reliable video content, High Speed internet access at hotels just now getting up to speed to deliver speeds for hotel wide video viewing.
The average TV viewing time in a hotel room is just 2 hours max. Between 6-7 am and 7-8 pm. all other ad delivery times (profits) are wasted. Advertisers know this but TIVUS investors seem to not know.
Miracast will be part of the game changer, oddly enough dumb TV's are the future, all people need is a large screen to view their own personal content with. We will watch our small screen on airplanes, busses, auto's but we will demand large screens in hotel rooms.
