How did I post this news before TechCrunch? Of course, it helps that I'm not living on the west coast where it's 4:30 am right now.
One of my friends already speculated that they bought CNET just so they could get the domain name tv.com. Nice.
It's a pretty bold move. CNET is widely looked at as a fix-it job and integrations after acquisitions are always a ton of work even when they go smoothly.
Best of luck to both CBS and CNET!
