I recall many a purchase that was killed. Modern day, Google has taken over that role.

Look at Microsoft acquisitions of late - Yammer and Skype being two of the larger ones that come to mind. Still there and running.

Skype may still be running but their service has become significantly worse after the centralized all the servers instead of the previous P2P architecture. At least I can clearly tell the difference.

I've had the opposite, the service has improved since MS bought them, I suspect thats because I'm in the continental US, and networkwise close to the datacenters Microsoft/Skype is using.

It seems more reliable in China too.
