Jack Dorsey Explains Why Twitter Isn’t ‘Twttr’

(Bloomberg) -- When the @Twitter handle asked followers earlier today to explain the meaning behind their Twitter handles, it got a slew of responses -- including from its founder, Jack Dorsey.

Later, though, in response to a question from a follower about the word “TWTR” -- the company’s ticker -- Jack delved a little deeper into the thinking behind the name of the now-$22.8 billion-dollar company.

A short code is a five- or six-digit number that acts as a shortcut to let cell-phone users opt in quickly to access added services -- for example, offers or promotions -- instead of using the usual seven digits (plus area code).

Dorsey’s first ever tweet, sent March 21, 2006 said “Just setting up my twttr.”
