"I'm a PC" is the title for a television advertising campaign created for Microsoft by ad agency Crispin Porter + Bogusky (CPB). The series first began to appear in September, 2008.[1][2] The new series of commercials replace those that featured the pairing of Jerry Seinfeld and Bill Gates.

The $300 million advertising campaign was designed to challenge Apple's Get a Mac campaign by showing everyday people to be PC users.[3]
