Twitter Inc. (TWTR), which operates the popular global messaging platform, was founded in 2006 from the ashes of another startup by Jack Dorsey, Evan Williams, Biz Stone and Noah Glass. Originally, Twitter developer Glass had created a venture called Odeo, a pioneer in podcasting, which soured. Glass then joined with his three colleagues to create Twitter. Since then, Twitter has grown into one of the world's premier news and social networking companies, with its tweets posted on the Internet and all forms of media. Twitter also offers the mobile app Periscope, which allows users to broadcast live videos.

Twitter's messaging platform has about 152 million average monetizable daily active users as of the three-month period ending December 31, 2019. The company generated $1.3 billion in net income on revenue of $3.5 billion in the trailing 12-month period to June 1, 2020. Twitter has a market cap of about $25.0 billion. Twitter primarily generates revenue through advertising, and a second revenue stream includes data licensing and other services.
