Last week was developer Christmas, or Google I/O. But Santa—AKA Sergey Brin—didn't bring Glass news or the latest flavor of Android (Key Lime Pie).

Google did deliver a new Play store, All Access music, a new Google+, and plenty of APIs.

Google also gave marketers more ways to put their brand in users' hands.

What marketers need to know...

At I/O, Google introduced tools for better and faster development and user-centric design.

Retailers, restaurants, and services can now offer special discounts in Maps listings and get recommended in Google Now's voice search results.

Tons of announcements for iOS and Android products shows they're committed to improving the user experience across platforms.
