Twitter

Twitter is a website, owned and operated by Twitter Inc., which offers a social networking and microbloggin service which enables its users to send and read other users' messages called tweets. 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. Twitter's origins lie in a "daylong brainstorming session" that was held by board members of the podcasting company Odeo. During the meeting, Jack Dorsey introduced the idea of an individual using an SMS service to communicate with a small group, a concept partially inspired by the SMS group messaging service TXT Mob. Twitter raised over US$57 million from venture capitalist growth funding, although exact numbers are not publicly disclosed.
