Bleemcast
Bleem was a promising commercial Playstation emulator which first appeared in 1999. It was a relatively small emulator which could run many games pretty fast. Two versions of Bleem were available, a demo version and the full version which required a CD key to function.
David vs. Goliath
Because Bleem tried to commercially exploit it's Playstation emulator, it was a prime target for Sony (the creators of the Playstation) to sue. After all in Bleem's case there was an actual entity to sue (the company) whereas the authors of freeware emulators are much harder to sue because it's not always clear who "owns" freeware emulators.
Bleemcast
One of the last products Bleem released was Bleemcast, an emulator for the Dreamcast which allowed owners of Sega's Dreamcast to play a few popular Playstation games on it. Unfortunately the Dreamcast was abandoned by it's creator, Sega, which left Bleemcast without a system to run on.
Gone the way of the Dodo
Although Bleem won most of the lawsuits launched against it by Sony, Bleem lost a lot of time and money in court due to these lawsuits. Combined with the lack of succes of their Bleemcast product and the fact that many gamers were moving on to newer, better systems eventually lead to Bleem's demise. As of November 2001, Bleem is no more.
