Twitter: born from a podcasting company's crisis

What happened
Odeo was a podcasting start-up co-founded by Evan Williams and Noah Glass. In 2005 Apple added podcasts to iTunes, making Odeo's product largely redundant. The team looked for a new direction through brainstorming sessions.
Jack Dorsey proposed a service for sharing short status updates by SMS. The prototype, ‘twttr’, launched in 2006 with a 140-character limit shaped by text-message length. Growth was slow until the South by Southwest conference in March 2007, where large screens displayed tweets and usage reportedly tripled from about 20,000 to 60,000 tweets a day.
Twitter became central to news, politics, and celebrity. It went public in 2013 but struggled to grow users and profits consistently. Elon Musk bought it for about $44 billion in 2022 and renamed it X.
