When the Clinton administration first got around to setting up a Whitehouse website in 1994, they had to go with whitehouse.gov because whitehouse.com was already taken, as a porn site.
For many years it was a porn site. Now it is a political betting and polling site.
In the Clinton years, Whitehouse.gov was the official White House website.
Whitehouse.com was the porn site.
The White House was also a porn site.
