Snapchat, the fast emerging mobile messaging app, is reported at 6 billion video daily views, tripling since last May. With Facebook’s views sitting at 8 billion, Snapchat is catching up faster than expected. In 2013, Snapchat turned down a $3Bn acquisition offer from Facebook, and is now valued at $19B. According to Snapchat, more than 60% of 13-34 year-old smartphone owners in the US use it.
