1975's groovy look
Just one glance at this logo makes it clear that it was designed smack in the middle of the '70s -- when Bill Gates and Paul Allen founded Microsoft in Albuquerque. The look lasted through the rest of the "Me Decade," but along with disco balls and vinyl suits, its reign came to a screeching halt at the start of the '80s.
