About the Company:

Twitter is a real-time information network powered by people all around the world that lets you share and discover what’s happening now.

Twitter asks “what’s happening” and makes the answer spread across the globe to millions, immediately.

What Twitter Does

Whether it’s breaking news, a local traffic jam, a deal at your favorite shop or a funny pick-me-up from a friend, Twitter keeps you informed with what matters most to you today and helps you discover what might matter to you most tomorrow.

The timely bits of information that spread through Twitter can help you make better choices and decisions and, should you so desire, creates a platform for you to influence what’s being talked about around the world. Search results spread across Twitter and in other ways across the Web so you can discover what’s happening on and off of Twitter.com, wherever you prefer.

Twitter can give a voice to even the weakest signals because of its simplicity. Users can access Twitter on powerful broadband connections via a video game console or through faint connections in rural areas via SMS on a simple mobile phone. You can also access Twitter through more than 50,000 third-party Internet and mobile applications.

Just remember, how you use Twitter is completely up to you. Follow hundreds of people. Follow a dozen. Post every hour. Post never. Search for your favorite topics and create lists. Or not. You are in control on Twitter.
