OnLive and OnMobile are entirely different companies in different domains, different geographical spreads, different sizes. But they have quite a few similarities as well. While the  “On” in their names is an obvious similarity, the stories of their misfortunes also strike an unfortunate likeliness.
OnMobile was founded by Arvind Rao who led it to tremendous heights as its CEO, before falling to his own success. OnLive was led by Steve Perlman who had quite an awesome pedigree before he founded the company. OnLive has been having its share of bad times of late.
