The two most popular social media sites in the world today are Facebook and Twitter. Some business houses are advertising their products and services on social media. Twitter gained popularity in social media as it enabled users to send short burst messages to the world hoping someone would look at the message (tweet) and respond. Initially, tweet messages were limited to sending 140 character messages. People started following messages on their topic of interest and also started following messages of people that they liked, for example, celebrities, sportspersons, and politicians.
Recently in America, the world witnessed US President Donald Trump's addiction of broadcasting his views on the world and domestic affairs on Twitter. In fact, some of his tweets created quite a stir and criticism as well.
Twitter has become one of the favorite social media tools among people to air their views on any topic they choose. Because of the character limitation users are forced to write short and meaningful messages. Also, the fact that its a free broadcaster and receiver has made it hugely popular. Most people use it as a recreational tool, but some people write and broadcast useful messages.
