Free-to-air television

Galaxy 18 is the home of a number of minor television networks, and in the past hosted the stations of Equity Media Holdings before its 2009 bankruptcy, where it used the satellite to beam several major network affiliates to their appropriate local transmitters, along with the local cable providers carrying them as Equity hubbed their master control from a hub in Little Rock, Arkansas.
