Instagram

Instagram is the new "it" thing for the younger set. They use the app to share photos and thoughts with friends. But this week we heard that Instagram could be selling your photos to businesses to use in ads.

News broke on Monday that Facebook had acquired the popular photo-sharing service Instagram for the princely sum of $1 billion in cash and stock. It’s the biggest purchase in the history of the world’s largest social network, and it made new multimillionaires of Instagram’s chief executive and the company’s handful of employees.
