The Evolution of company logos VII

In 1975, Paul Allen (who then was working at Honeywell) and his friend Bill Gates (then a sophomore at Harvard University) saw a new Altair 8800 of Micro Instrumentation and Telemetry Systems or MITS. It was the first mini personal computer available commercially.

Allen and Gates decided to port the computer language BASIC for the computer (they did this in 24 hours!), making it the first computer language written for a personal computer. They approached MITS and ended up licensing BASIC to the company. Shortly afterwards, Allen and Gates named their partnership "Micro-soft" (within the year, they dropped the hyphen). In 1977, Microsoft became an official company with Allen and Gates first sharing the title general partners.

On to the logo history:

In 1982, Microsoft announced a new logo, complete with the distinctive "O" that employees dubbed the "Blibbet." When the logo was changed in 1987, Microsoft employee Larry Osterman launched a "Save the Blibbet" campaign but to no avail. Supposedly, way back when, Microsoft cafeteria served "Blibbet Burger," a double cheeseburger with bacon.

In 1987, Scott Baker designed the current, so-called "Pac-Man Logo" for Microsoft. The new logo has a slash on the ‘O’ that made it look like Pac-Man, hence the name. In 1994 Microsoft introduced a new tagline Where do you want to go today?, as part of a $100 million advertising campaign. Needless to say, it was widely mocked.

In 1996, perhaps tired of being the butt of jokes like "what kind of error messages would you like today?", Microsoft dropped the slogan. Later, it tried on new taglines like "Making It Easier", "Start Something", "People Ready" and "Open Up Your Digital Life" before settling on the current "Your potential. Our passion."

Oh, one more thing: what was Microsoft’s original slogan? It was "Microsoft: What’s a microprocessor without it?"

… Microsoft’s very first advertising campaign "Microsoft: What’s a microprocessor without it?," which touted how Microsoft’s line of programming languages could be used to create software that would take advantage of the early microprocessors. The first advertisement in the campaign appeared in a 1976 issue of a microchip journal called Digital Design and featured a four panel black-and-white cartoon titled "The Legend of Micro-Kid." The cartoon depicted a small microchip character as a boxer who possessed speed and power but quickly tired out because he had no real training. The other character, a trainer complete with a derby on his head and big stogie hanging out of his mouth, related the story of how the Micro-Kid had a great future but needed a manager, such as himself, in order to succeed.
