Snap, owner of the Snapchat messaging app popular with teenagers, has announced it will sell its shares on the US stock market.
While the company itself is loss-making, some users are making money from the platform.
People like Tanner Fox, a social media star with more than three million followers on YouTube and a six-figure following on Snapchat.
