WBNS-TV began operations on October 5, 1949. WBNS radio had been a CBS Radio Network affiliate for almost 20 years, so channel 10 immediately joined the CBS television network. It is currently the ninth longest-tenured CBS affiliate. Channel 10 has used the on-air branding of 10TV since 1977. It is also one of only a few stations in the country to have had the same owner, call letters and primary network affiliation throughout its history, as well as the only major station in the city still owned by Ohio interests.
