This colorful logo debuted in the late 1960s, and was used until December 31, 1975. It is interesting to observe that the CBS eye is no longer a part of the graphic; this was the result of an edict from CBS to separate the non-O&O CBS station's news from being confused with the CBS network news operations. This 'unbranding' lasted for many years until competition from cable and satellite made CBS and the other networks urge affiliates to reincorporate the network ID into local promotion and news.
1976 was America's Bicentennial. In honor of the year, 'Big 13' becomes the 'Original 13.'
On December 12, 1994, WTVT switched affiliations from CBS to Fox, sending CBS programming to WTSP.
