Twitter is a microblogging and social networking service on which users post and interact with messages known as «tweets». Tweets were originally restricted to 140 characters, but on November 7, 2017, this limit was doubled to 280 for all languages except Chinese, Japanese, and Korean. Registered users can post, like, and retweet tweets, but unregistered users can only read them.
Twitter was created in March 2006 by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams, launched in July of that year. The service rapidly gained worldwide popularity. In 2012, more than 100 million users posted 340 million tweets a day, and the service handled an average of 1.6 billion search queries per day. In 2013, it was one of the ten most-visited websites and has been described as «the SMS of the Internet». As of 2018, Twitter had more than 321 million monthly active users.
Twitter has become internationally identifiable by its signature bird logo, or the Twitter Bird. The original logo, which was simply the word «Twitter», was in use from its launch in March 2006. It was accompanied by an image of a bird which was later disocvered to be a piece of clip art created by the British graphic designer Simon Oxley.
A new logo had to be redesigned by founder Biz Stone with help from designer Philip Pascuzzo, which resulted in a more cartoon-like bird in 2009. This version had been dubbed «Larry the Bird» specifically named after Larry Bird of the NBA’s Boston Celtics fame. Within a year, Larry the Bird logo underwent a redesign by Stone and Pascuzzo to eliminate the cartoon features, leaving a solid silhouette of Larry the Bird that was used from 2010 through 2012. In 2012, Douglas Bowman created a further simplified version of Larry the Bird, keeping the solid silhouette but making it more similar to a mountain bluebird. This new logo was called simply the «Twitter Bird,» and has been used as the company’s branding since..
