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.

The station signed on the air on January 24, 1972, with the call letters WRIP-TV. It aired an analog signal on UHF channel 61, and was sister station to WRIP radio in Rossville, Georgia (AM 980, now WDYN and FM 105.5, now WRXR). Signing on nearly five years after the construction permit was granted in March 1967, it was Tennessee's second independent station, having launched a little over nine months after the state's first independent, WMCV in Nashville, went off the air but only to return in 1976 as WZTV. It is the state's oldest television station in continuous operation to have never had affiliation with any of the big three networks (ABC, CBS, and NBC). The station was owned by Jay Sadow.

Initially, WRIP was positioned as an all-movie station. Therefore, early programming on WRIP included older movies from the 1930s to early 1960s for most of its broadcast day along with some theatrical cartoons and shorts. These selections included Little Rascals, Three Stooges, and Looney Tunes. The station was on-the-air for about twelve hours a day signing on at noon. By the summer the station was on 19 hours a day signing on at 7 a.m.

The station was plagued by financial problems for several reasons. It was a UHF station serving a small market in a very mountainous area. In analog days, UHF stations, especially those on high channel numbers, usually did not get good reception more than about 30 miles (48 km) away in rugged terrain. Also, the station was losing money because it overspent on movie packages. The station was locally owned and its owner did not have the money to spend on any other programming investments. In the course of 1973, WRIP-TV gradually shifted to a somewhat traditional independent station schedule of programs but with a low-budget approach.

By 1974, it added low-budget cartoons, low-budget syndicated shows such as wildlife and sporting shows, and locally based religious shows. That year, the station eliminated movies as well as cutting hours on the air, signing on at 3 p.m. and off the air by midnight. In the fall of 1974 it expanded the broadcast day slightly and added a run of the ninety-minute edition of The 700 Club in 1975 and two runs of the two-hour version of the PTL Club. The station then began selling huge blocks of time to mostly churches in the local area cutting back more on low-budget secular shows.

By 1976, the station was running mostly Christian programs about twelve hours a day along with some low-budget secular programs such as children's programs (including The New Zoo Revue, Devlin, and Gigantor), outdoor sporting and hunting shows, The Mike Douglas Show, as well as some low budget instructional shows about four hours a day. The station was basically profitable by selling thirty- and sixty-minute blocks of time most of the day to local religious broadcasters.
