WDSI-TV (channel 61) is a television station in Chattanooga, Tennessee, United States, affiliated with True Crime Network and Comet. The station is owned by New Age Media, which also operates Cleveland-licensed dual CW/MyNetworkTV affiliate WFLI-TV (channel 53) under a local marketing agreement (LMA) with MPS Media. Sinclair Broadcast Group, owner of dual ABC/Fox affiliate WTVC (channel 9), provides some engineering functions for both stations under a master service agreement and also programs WFLI-TV.
WDSI-TV and WFLI-TV share studios on East Main Street (SR 8/US 41/US 76) in Chattanooga's Highland Park section; master control and some internal operations for the two stations are based at WTVC's facilities on Benton Drive in Chattanooga. WDSI-TV's transmitter is located on Signal Mountain in the town of Walden.
Established in 1972 as independent station WRIP-TV, channel 61 later became WDSI-TV in 1983. The station was a Fox affiliate from 1986 to 2015, when Sinclair purchased the programming assets of New Age Media's Chattanooga stations but did not assume program control of WDSI-TV.
