As funny as that billboard is, it's horrible marketing.
All you see at any distance is a console and the word Sega in big letters.
Amiga and CD32 are in tiny little letters that aren't readable in the photo.
Also, I wonder how much it cost them in extra legal mumbo-jumbo to see if they would be sued for doing a stunt that nobody really cared about and didn't increase sales?
It's amazing Commodore survived into the 90's at all.
