The next chapter of Snapchat's life will begin over the coming months, as parent company Snap, Inc. goes public with an initial offering that could value the firm at approximately $20 billion.

Snapchat's once-meteoric growth is showing signs of slowing, with only 8 million new users over the last six months.
