In the world of apps, it is hook, line, and sinker. After SnapChat hooked over 1.7 million Facebook users, lined them in with a snazzy free app, the company is now looking to hook  them with ads.  “There’s a couple of things we are really excited about right now. There are a lot of businesses experimenting with SnapChat,” Spiegel said. “What I’m really excited about is this really awesome new ad format we’ve been experimenting with. We think it’s really engaging. We think when ads are done right, they can be informative and delightful and we are really excited about that,” SnapChat CEO Evan Spiegel told CNBC. [Source: CNBC]
