Apple has signed a pact with a Japanese marketer, The Dentsu Group, to bring the iAd platform to Japan in early 2011. Under the new arrangement, Dentsu will be responsible for the selling and "creative execution" of iAd spots in Japan. Apple's role will be limited to hosting and delivering ads, as well as targeting them in the first place. Dentsu claims to be the "world's top brand agency," with over 6,000 clients and just under 20,000 workers.
