GoogleはさきほどAdMobを$750M(7億5千万ドル)で買収したことを発表した。AdMobは携帯電話、特にiPhoneで大きなシェアを占める広告ネットワークだ。Sequoia Capital、Accel Partnersなど初期の投資家にとっては大勝利の日となった。 (Accelにとっては特にそうだ―EAが買収したPlayfishにも投資している)。その後、Draper, Fisher, JurvetsonとNorthgate Capitalも出資している。

Today we announced that AdMob has signed a definitive agreement to be acquired by Google for $750 million. We are extremely excited about this new partnership and what it means for our advertiser, developer and publisher partners.

AdMob’s people, products and tools will continue to work to deliver successful campaigns for you and to effectively monetize your mobile traffic – no interruptions. Our product and engineering teams will keep building great products for our customers. Our sales team will keep working with our thousands of advertisers to deliver successful campaigns. Our business development team will keep working to maximize ad revenue for the more than 15,000 mobile Web sites and applications that make up AdMob’s publisher network.

After our deal closes, AdMob will work with Google to accelerate the pace of innovation in mobile and do an even better job for you. We believe this deal will benefit our advertisers, developers and publishers by:

*Increasing our investment in building innovative and engaging ad units across platforms and to further improve targeting and tracking.

*Building even more powerful relevance and optimization capabilities, and more powerful technology and tools to monetize mobile traffic.

*Increasing the effectiveness of display advertising on mobile devices by leveraging Google sales team, infrastructure and relationships.

This has been a big day for acquisitions. Earlier today we broke the story that Google is acquiring VoIP startup Gizmo5 for around $30 million in cash.
