Twitter has introduced a new ecommerce feature called @earlybird which offers "special time-bound deals, sneak-peeks, and events."

"We partner with select advertisers and retweet offers that they have crafted only for the Twitter community," the company said.

"Our advertising partners determine the terms of the offer, including availability, amount, and price. As with other forms of advertising from Twitter, we are focused on bringing value to our users and will keep your interests in mind as we develop this program."

Twitter said it launched @earlybird because many users find the site timely and that it has relevant information. "We believe that surfacing deals through the @earlybird account will help you discover the best of those deals, as well as find and follow accounts that consistently provide exceptional value," Twitter said.

Twitter did not name any advertisers or brands but did say they would large brands initially focused on the U.S. market. The company said @earlybird will feature US-wide offers but it will consider location-based deals in the future.
