PayPal is the most common service in the world of Internet payments. Today, PayPal is used by more than 230 million people in 190 countries. It was founded in 1998 by the American programmers Peter Thiel, Luc Nosekom, Luke Nosek, and the Kyiv‑born Max Levchin. In 2004, the service was purchased by eBay for 1.5 billion dollars. Afterwards, Max Levchyn created the startup, Slide, a service for displaying a large number of photos, which paired with the MySpace social network. Later, Slide switched to creating social services for MySpace and Facebook. In August 2010, Google acquired Slide for 182 million dollars.
