WBXX-TV (channel 20) is a television station licensed to Crossville, Tennessee, United States, serving the Knoxville area as an affiliate of The CW and Telemundo.

The two stations share studios on Papermill Drive (near I-40/I-75) on the west side of Knoxville; WBXX-TV's transmitter is located at Windrock, Buffalo Mountain outside Oliver Springs, Tennessee.

CW applied to move the transmitter site to Upper Windrock, an outcropping on Buffalo Mountain along the Cumberland Plateau above Oliver Springs, Tennessee, and boost power to 3,630 kW—covering Knoxville.

ACME immediately changed the call letters to WBXX-TV, and in October 1997, channel 20 relaunched from its new facilities as Knoxville's affiliate of The WB.

The interstitials featured information and contests to viewers in several vignettes each weekday covering topics such as science, biology, conservation, music, and pet care.

From 2015 to 2019, WBXX has broadcast Atlantic Coast Conference football and men's basketball games syndicated from the Raycom Sports–operated ACC Network, some of which were shared with the main channel of CBS affiliate WVLT-TV.

[19] On June 25, 2018, Gray Television announced that they would acquire the assets of Raycom Media, who had been owned Fox affiliate WTNZ-TV since 1996 for $3.6 billion.

The program was produced by ACME Communications, and during the company's ownership of this station, there were local weather cut-ins focusing on the Knoxville area.

The newscast only aired for twelve minutes in an abbreviated format featuring the day's top stories along with an updated weather forecast.

Corresponding with the addition, WATE upgraded to high definition newscasts that October 17 becoming the third local news operation in Knoxville to make the change.
