About

Twitter is the best way to discover what’s new in your world.

An information network

Twitter is a real-time information network that connects you to the latest information about what you find interesting. Simply find the public streams you find most compelling and follow the conversations.

At the heart of Twitter are small bursts of information called Tweets. Each Tweet is 140 characters in length, but don’t let the small size fool you—you can share a lot with a little space. Connected to each Tweet is a rich details pane that provides additional information, deeper context and embedded media. You can tell your story within your Tweet, or you can think of a Tweet as the headline, and use the details pane to tell the rest with photos, videos and other media content. See it in action.

You don’t have to tweet to get value from Twitter

You don’t have to build a web page to surf the web and you don’t have to tweet to enjoy Twitter. Whether you tweet 100 times a day or never, you still have access to the voices and information surrounding what interests you. You can contribute, or just listen in and retrieve up to the second information. Some people never tweet, they simply use Twitter as a way to get the latest information on their interests.

Twitter for Businesses

Twitter connects businesses to customers in real-time. Businesses use Twitter to quickly share information with people interested in their products and services, gather real-time market intelligence and feedback, and build relationships with customers, partners and influential people. From brand lift, to CRM, to direct sales, Twitter offers businesses a chance to reach an engaged audience.
