Twitter lets you write and read messages of up to 140 characters, or
the very length of this sentence, including all punctuation and spaces. The messages are public and you decide what sort of messages you want to receive—Twitter being a recipient driven information network. In addition, you can send and receive Twitter messages, or tweets, equally well from your desktop or your mobile phone. Have you ever tried to figure out why there is 140 character limit in twitter if yes than this post may help you.
A brief history of Twitter
Initially inspired by the concept of an ‘away-message’ merged with the freedom and mobility of SMS, Twitter began as an experiment in 2006. When value as an instant communication network during shared events like earthquakes, conferences, and festivals emerged, Twitter began to grow—Twitter, Inc. was founded in 2007. Today, Twitter is a privately funded company based in San Francisco, CA.

As mentioned Twitter is capable of tweeting from your mobile and you can even receive tweets on your mobile phones as SMS. And this is the reason why there is a 140 characters limit in twitter.
Why 140 characters?

SMS (i.e., texting on your phone) limits each message to 160 characters. Twitter takes that limit and reserves 20 characters for your username, leaving you 140 characters to play with. That’s how it started and we’ve stuck with it!

If you work around with Twitter website you will come to know about it. There wasnt a need of such a big post for such a small answer.
There are also other services allowing only 140 characters. Personally I prefer Brightkite. Very similar to Twitter although you can dirctly post also pics and comments.
