Twitter is a social media platform founded in 2006 by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams. It is designed for microblogging, allowing users to share short messages called “tweets” with a character limit that initially started at 140 and later expanded to 280. Twitter has become a major platform for news, public discourse, and real-time conversations, often used by individuals, brands, celebrities, and politicians to connect with a global audience.

The platform is known for its hashtag system, enabling users to follow specific topics, trends, and events. It plays a critical role in real-time communication, especially during breaking news events, political debates, and social movements. Twitter’s features include retweets, replies, quote tweets, lists, direct messaging, and spaces for live audio conversations. It has become a hub for sharing opinions, news stories, memes, and social campaigns, making it influential in shaping public opinion and media narratives.

In 2022, Twitter was acquired by Elon Musk, resulting in significant changes to the platform's operations, features, and monetization strategies, including a subscription-based verification system and new content policies. It has also undergone a rebranding to X, focusing on transforming into a more comprehensive platform beyond microblogging, including features like longer posts, payments, and extended videos.

However, Twitter has faced challenges regarding misinformation, harassment, privacy, and bots. To combat these issues, Twitter has implemented measures such as labeling misleading content, fact-checking partnerships, and updating community guidelines to maintain transparency and accountability.
