It appears that Google is headed after the mobile ad space pretty heavily. From a post on the Official Google Blog today:
We’re happy to announce today that we have signed an agreement to acquire AdMob, a mobile display advertising company based in San Mateo, CA. AdMob is a great Silicon Valley story — founded in 2006 by Omar Hamoui when he couldn’t find good ways to generate traffic for his mobile site. Over the past few years, Omar and his talented team have built a thriving company with great mobile advertising products, and we are looking forward to having them join the Google team and work with us on the future of mobile advertising.
What does this mean for mobile advertising?
For publishers of mobile websites and applications, this deal will mean better products and tools and more effective monetization of their content — allowing them to focus more on their users and less on how to generate revenue.
For advertisers who want to reach users when they are engaged with mobile content, this deal will bring better, more relevant ads and greater reach. It will also mean more interesting, engaging ad formats.
