Vine -- the mobile app to create six-second, looping videos -- has grown to more than 40 million users in its first year.
Launched one year ago today, co-founder Colin Kroll said the goal was to make finding, watching and sharing videos easier from people's smartphones.
"We had no idea what people would do with it, and every day we're blown away by the creativity, comedy and momentous events we see captured on Vine," Kroll said in an e-mailed response to USA TODAY Network.
