Ted Turner (CNN) used to have a Citation 650. Not sure if he still does. Gannett (USAToday owner) has a large flight department. GE owns one of the networks, NBC I think. They have a large flight department.
I believe a number of stations/networks may have flight departmetns, but finding them could be a challenge as it could be under a parent corporation or subsidiary.
