Snapchat is a multimedia messaging app used globally, created by Evan Spiegel, Bobby Murphy, and Reggie Brown, former students at Stanford University, and developed by Snap Inc., originally Snapchat Inc. One of the principal features of Snapchat is that pictures and messages are usually only available for a short time before they become inaccessible to their recipients. The app has evolved from originally focusing on person-to-person photo sharing to presently featuring users' "Stories" of 24 hours of chronological content, along with "Discover", letting brands show ad-supported short-form content.

Lawyers for Snapchat responded by insisting that he had never had any creative connection to the product. The attorneys also accused Brown of committing fraud against Spiegel and Murphy by falsely claiming to be a product inventor. On behalf of their clients, the law firm concluded that Reggie Brown had made no contributions of value or worth, and was therefore entitled to a share of nothing. In September 2014, Brown settled with Spiegel and Murphy for $157.5 million and was credited as one of the original authors of Snapchat.In their first blog post, dated May 9, 2012, CEO Evan Spiegel described the company's mission: "Snapchat isn’t about c
