Twitter is a website, owned and operated by Twitter Inc., which
offers a social networking and microblogging service, enabling its users
to send and read other users' messages called tweets. Tweets are
text-based posts of up to 140 characters displayed on the user's profile
page. Tweets are publicly visible by default, however senders can
restrict message delivery to their friends list. Users may subscribe to
other author tweets—this is known as following and subscribers are known
as followers. As of late 2009, users can follow lists of authors instead
of just following individual authors.
All users can send and receive tweets via the Twitter website,
compatible external applications (such as for smartphones), or by Short
Message Service (SMS) available in certain countries. While the service
is free, accessing it through SMS may incur phone service provider fees.
The website is based in San Bruno, California near San Francisco (where
the website was first based). Twitter also has servers and offices in
San Antonio, Texas and Boston, Massachusetts.
Since its creation in 2006 by Jack Dorsey, Twitter has gained
popularity worldwide and currently has more than 100 million users. It
is sometimes described as the "SMS of the Internet.".
