Twitter is the name of a popular online social network.
Formed in March 2006 by Jack, Williams, Biz Stone and Noah, Twitter is
an online social networking service, made up of 140-character message
extensively known as Tweet. Twitter started its formal journey by July
2006. Feelings, news or information of any kind are shared through
tweets. Today Twitter has at least 500 million users. Among the
registered users, the number of active users is more than 300 million.
Short messages are sent and read by users via Twitter. Twitter gained
worldwide recognition radically. Twitter is also known as “the SMS of
the Internet.” Registered users are allowed to read and post tweets.
Unregistered users can not tweet but they have access to read the tweets
posted by others.
An undergraduate student of New York University named Jack Dorsey
communicated with a small group by means of SMS. “Twttr” was the code of
the service, idea of which Evan Williams attributed to Noah Glass
later. The source of their inspiration to use the service was Flickr and
five-character American SMS short codes.--Know More
