Social media platform Snapchat may have crept up on you but with 100 million daily users and 8 billion video views per day, the pressure is now on grown-ups and companies to start using it.
It's the preferred social media platform for millennials -- those born in the 1980s and 1990s - and allows you to send a "snap" – a picture or video – to people. As soon as someone reads the snap, it disappears. But users can also post a "story" – a public collection of snaps that disappear after 24 hours.
Using Snapchat can be baffling to many, but never fear, CNBC has this handy guide.
