CNET used to do something sneaky whereby they used domain.com.com on many of their domains to inflate their unique visitor counts. That way, when somebody typed http://mistake.com.com, they'd be counted as a unique visitor to the com.com TLD which hosted all CNET sites. This way, they could tell advertisers that they reached 99% of the Internet via their com.com domain. It was really annoying to type in http://www.cnet.com, and be redirected to http://cnet.com.com...
Apparently, they've stopped doing this. Now, typing in, say, http://mistake.com.com ends up doing a search for "mistake" on CNET's search engine, search.com.
