Event Horizons BBS was a popular and perhaps the most financially successful Bulletin Board System (BBS). It was founded in 1983 by Jim Maxey, who was President and CEO and ran his company out of Lake Oswego, Oregon. In 1994 Maxey closed the BBS.
Event Horizons BBS originally offered online forums, games, and astronomy images for paying customers to download. Maxey first charged $1/hr which grew over the years to $24/hr. The BBS later offered softcore adult images and movies which helped to secure its fame as the most profitable BBS.
In 1992 Playboy Enterprises sued Event Horizons for copyright infringement. Maxey reportedly paid Playboy a half million dollars to settle the case out of court.
