More than two dozen network-affiliated Hearst Television stations went dark on the satcaster tonight after the sides hit a wall in their retransmission talks. Dish Network‘s carriage deal with Hearst TV expired March 1, but the parties had extended the deadline to tonight at 7 PM Pacific. The blackout affects more than two dozen Hearst stations including ABC affil WCVB in Boston, the nation’s No. 7 TV market, and outlets in top 25 markets Sacramento, Pittsburgh and Tampa, FL. It comes the same day that the Weather Channel and satellite giant DirecTV settled their carriage dispute and seven months after Time Warner Cable and CBS settled their bitter retrans fight.
