On the1440.com every minute of the day is sold once. Whoever buys 18:40 UTC gets the whole front page from 18:40:00 to 18:40:59: their name in full-screen type, one line of copy and a link, with nothing else on the screen. It is a peak minute, so it costs $3.
Nothing yet. Every time 18:40 UTC has gone unsold, the1440.com showed dead air. The first name here is still up for grabs.
