Plastered across the bottom of the screen during the Altitude TV broadcast of the Denver Nuggets game against the Sacramento Kings on Monday night was the respective toll free numbers for Comcast, Direct TV and Dish Network, urging fans to call the networks and demand change. How many saw it? Impossible to tell. Altitude TV has gone dark on all three TV providers, the result of a contract dispute that has gone on for over a month. Those three television providers of course dominate the market share so the majority of Altitude’s viewers, and Nuggets fans, are left with very few options to watch the games.
