Twitter unveiled a new 'Twitterbird' on May 31, which will be the new trademark symbol for the fast-growing company. The new bird "grows out of love for ornithology, design within creative constraints, and simple geometry," Bowman said.
Twitter, which allows its members to post brief comments, links or pictures, claims to have more than 140 million active users, with the largest number being in the United States. A recent survey found one out of seven Americans who go online use Twitter and eight percent do it every day.
