As Vine grows, rubber ducks rule

The six-second video sharing app Vine turned three this month. Let's take a look at its most viewed clips of the past year. The app is best known for turning any heartthrob teenage boy with a smartphone into a superstar, and also feeding users' penchant for funny kid clips (boy-plus-avocado has 91 million loops). The "duck army" clip is still No. 2 with 154 million. The most watched clip, however, isn't funny: It's a screen rip of the France-Germany soccer match that was rocked by the sound of an explosion from the Paris terrorist attacks.
