Twitter advertising revenue halves since Elon Musk takeover-News First English

Twitter is a popular social media platform that allows users to post and interact with short messages called "tweets." It was founded in 2006 by Jack Dorsey, Biz Stone, and Evan Williams. Twitter enables users to follow other users and receive their updates in a chronological timeline. Users can also engage with tweets by liking, retweeting, or replying to them.

Twitter has become a significant platform for news, discussions, and networking, with users ranging from individuals to celebrities, businesses, and organizations. It has a character limit of 280 characters per tweet, although some features, such as quoting other tweets, allow users to exceed this limit.

Over time, Twitter has introduced various features and enhancements, including the ability to add images, videos, and GIFs to tweets. It has also introduced features like hashtags, which allow users to categorize and search for specific topics or trends.

In addition to its user-generated content, Twitter also generates revenue through advertising. Advertisers can promote their products, services, or messages through sponsored tweets, trends, or accounts. Twitter's advertising revenue comes from businesses and organizations that pay for these promotional opportunities.
