Kimsey changed the company's strategy, and in 1985, launched a dedicated online service for Commodore 64 and 128 computers, originally called Quantum Link ("Q-Link" for short). The Quantum Link software was based on software licensed from PlayNet, Inc, (founded in 1983 by Howard Goldberg and Dave Panzl). The service was different from other online services as it used the computing power of the Commodore 64 and the Apple II rather than just a "dumb" terminal. It passed tokens back and forth and provided a fixed price service tailored for home users. In May 1988, Quantum and Apple launched AppleLink Personal Edition for Apple II and Macintosh computers. In August 1988, Quantum launched PC Link, a service for IBM-compatible PCs developed in a joint venture with the Tandy Corporation. After the company parted ways with Apple in October 1989, Quantum changed the service's name to America Online. Case promoted and sold AOL as the online service for people unfamiliar with computers, in contrast to CompuServe, which was well established in the technical community.
