What is Twitter?
Twitter is an information network. Millions of people, organizations, and businesses use it to discover and share new information.

On Twitter, anyone can read, write and share messages of up to 140 characters. These messages, or Tweets, are public and available to anyone interested in them. Twitter users subscribe to your messages by following your account. Followers receive every one of your messages in their timeline, a feed of all the accounts they have subscribed to.
When you combine messages that are quick to write, easy to read, public, opt-in, and accessible anywhere, you have a powerful, real-time way of communicating.
What does Twitter do for businesses?
As a business, you can use Twitter to quickly share information, gather market intelligence and insights, and build relationships with people who care about your company. Often, there is already a conversation about your business happening on Twitter.

Most of you know that Twitter can be used for much more than just announcing what you ate for breakfast. Many of you already know Twitter’s value in business, but you can still take it further and use it to land gigs, market your business, grow your network and gain free publicity — all in 140 characters or less.
It’s true that Twitter is what you make of it. Some people publicize their daily activities, some make it about link love, some share quotes all day long. Smart people using Twitter for business mix it up.
