[2] On May 7, 2009, the KKTX-FM 96.1 FM simulcast ended when the station started syndicating Scott Shannon's "The True Oldies Channel and picking up the KDOK call sign dropped by 92.1 KTBB-FM in Tyler, Texas.

As of February 24, 2011, KDOK has dropped Scott Shannon's True Oldies Channel and it began stunting with Michael Jackson's "Beat It" on repeat.

In 1965, 1330 dropped the KDOK call letters after 9 years of running the top 40 format in favor of a switch to country.

In 1993, the KDOK call letters and format were moved from 1330 to 92.1 in Tyler (the former country "K-Rose" KROZ), where they lived for another 15 years as an oldies station.

In 2009, 92.1 dropped the KDOK call letters and oldies format to begin simulcasting sister station KTBB 600, becoming KTBB-FM.
