.TV was close, they launched and segregated a bunch of domains off as "premium" and charged inflated prices. Then there was (IIRC) an episode where they wanted to renew a bunch of landrush domains at "premium" prices. They also don't allow "premium" domains to switch registrars.

The new .WED rules are crazy. Year 3 renewal is $25,000. They think the next "Brad and Janet" want to be able to use BradAndJanet.WED for their wedding.
