From GigaOm today:

The iPhone App Store is red hot: In its first month, more than 60 million software programs were downloaded, and it generated about $1 million a day in sales. That information comes from Steve Jobs in an interview with The Wall Street Journal. In his interview, Jobs says the developers took home $21 million in the first month, of which $9 million went to the top 10 developers. One of the biggest selling app: Sega Corp’s $9.99 Super Monkeyball game, which sold more than 300,000 copies in 20 days. (iPhone as a gaming platform isn’t such a crazy idea after all!)…

That is a lot of Monkeyball!
