WTCB (106.7 FM) is a commercial radio station licensed to Orangeburg, South Carolina, and serving the Columbia metropolitan area.

WIGL made an effort to serve the larger, more lucrative Columbia radio market, but was plagued with periodical audio problems as well as fierce competition from established country station WCOS-FM.

By the late 1980s, due to changing market conditions, "B106" softened its music by dropping the more upbeat titles and focused on being a soft adult contemporary outlet.

From September 2002 until November 2007, WTCB was the flagship radio station for University of South Carolina Gamecocks football, taking over from longtime outlet WVOC.

When Citadel Broadcasting moved co-owned WNKT from the Charleston radio market to Columbia, it switched that station to an all sports format.

In 2015, WTCB moved to new studio in downtown Columbia, across from the State Capital in The Tower building currently anchored by the Bank of America.

WTCB shifted to a mainstream adult contemporary format playing current and past AC artists being inclusive of a younger demo.
