In the 11 years I ran Frog City, people often asked about the name (no-not French, not a frog lover, yes-a weak play on Fog City, the nickname for San Francisco).
So to get the name story out of the way: when I sold most of Frog City to Take-Two, including the name, I was left with a company with no name. I kept it alive as a potential side project. At the time, I was making up bed-time stories for my kids involving an invisible scooter with a sidecar that could only be seen and used by children.
The side project met the scooter stories, and gave rise to the name Sidecar Studios. The logo was made by a friend. I like the way it evokes the world of the imagination-the scooter is in motion, yet only the sidecar is occupied.
