WGBH TV Logo

 

WGBH's most famous and best known logo, consisting of the company name with a double drop shadow on both sides of it, was designed by Chermayeff & Geismar. This logo's first on-air appearance occurred on March 3, 1974, during the series premiere of Nova. A network ID was produced in 1977 by Chris Pullman.

Despite being replaced by the 2020 logo, this logo is still used in tandem with said logo, and was also used for on-screen variants until October 1, 2020.
