From Wikipedia:
PGA Tour is a series of golf video games developed and published by Electronic Arts - and later their EA Sports sub-label - since 1990. The series primarily features courses featured on the U.S. PGA Tour, and other notable courses (such as those that have hosted majors).
In 1998, EA began publishing their golf games with the endorsement of Tiger Woods. Following the Tiger Woods 99 PGA Tour Golf release, subsequent titles were named Tiger Woods PGA Tour and released yearly.
