Also, Google is making use of Android app streaming to reel you in to those games. It's offering a special marketing format, the Search Trial Run Ad, that lets you try Android games in the browser for up to 10 minutes -- you don't have to jump to the Play Store and download the title first. As you'd guess, you'll get an invitation to install the game afterward if you're enamored with the experience. While it's a calculated marketing ploy, it could help a lot if you've ever been curious about a game but didn't want to commit to installing the whole thing right away.
