And a list of the launch partners.
Apple announced today that its iAd mobile ads network will launch on 1st July, and already has $60 million spend committed by brands for the second half of this year.
CEO Steve Jobs listed the brands who have already signed up in the eight weeks since iAd was announced.
They include Nissan, Citi, Unilever, AT&T, Chanel, GE, Liberty Mutual, State Farm Insurance, Geico, Campbell's Soup, Sears, JCPenney, Target, Best Buy, DirecTV, TBS and Disney.
The US-centric nature of many of those brands may raise questions about whether iAd will launch in Europe at the same time - Jobs didn't mention geographic rollout in his keynote.
However, he did claim that iAd is on course to account for 48% of the US mobile display advertising market in the second half of this year, basing that claim on figures from JP Morgan suggesting the market will be worth $250 million for 2010 as a whole.

"We're trying to combine the emotion of video with the interactivity of the web. This is what advertisers have been after in the digital advertising medium," said Jobs.

EDIT - Apologies for the initial headline typo - it is of course $60 million, not $60 billion.
