I was looking at production company logos and came across the WGBH Boston logo and I want to know more about it? The earlier version of the WGBH Boston logo has an orange color and features odd music while the words WGBH Boston Presents appear. I often wondered if WGBH Boston sued Procter And Gamble Productions for copying their logo because I think this logo inspired Procter And Gamble Productions Logo that was used from the 80's to the 2000's. When did WGBH Boston debut this logo and is there a newer version of it too?
