Twitter, a popular social media platform that allows users to send and share short messages. Twitter began as a microblogging service that allowed users to share text of up to 280 characters. Additionally, users could share various content types such as media files, GIFs, and videos.

Twitter has evolved into a broad social network that allows users to follow news, share their thoughts, and interact with other users. Celebrities, politicians, companies, and brands also use Twitter as part of their marketing and communication strategies. However, I recommend referring to current sources for detailed and up-to-date information.
