Sorry, didn't know the Doomsday Clock was displaying pop-up ads. Kind of makes it look like there's 67 days until the Three Stooges DVD comes out, doesn't it? (I really must learn to test these things in something other than Firefox for Mac with Ad-Blocker Plus installed!)
I don't believe in ads (at least not on this site). Also, there was supposed to be a message displayed when the clock ran out... nothing like obscuring that with an ad for the Jupiter Jack.
So the site is still ending on Super Bowl Sunday, but for now - it's goodbye clock. I'll hunt around for a better one.
