Sinclair Broadcast Group owned both the Fox and WB affiliates in the DMA prior to the September 2006 merger of UPN and WB into a newly created CW Network and was forced by Fox to convert its WB affiliate (WDKA) into a MyNetworkTV affiliate (MY49) . This allowed Raycom Media, owner of the local CBS and UPN affiliates, to convert its UPN affiliation (WQWQ) to The CW. WQWQ is a low-power station whose analog signal was never available over the air in Dahlgren; however, it is available as ATSC digital channel 12.2. With the digital TV transition RTV, formerly ion Television/PAX, (WPXS) moved its transmitter northwest of Breese, IL in the St. Louis, MO DMA and is no longer easily available over-the-air in Dahlgren. Viewers with a rotator and suitably elevated antenna can also receive virtually all over-the-air broadcasts from Evansville, Indiana.
Cable television service (analog), previously available from Longview Communication, was terminated in 2006. Hamilton County Communications (a wholly controlled subsidiary of the Hamilton County Telephone Cooperative) purchased the cable-operating rights from Longview in 2006 although it is unclear whether they will be able to operate a cable system under current FCC rules. HCC distribute digital TV using broadband internet.
