Black Twitter is a cultural identity comprising the African-American Twitter users. In other words, it is a virtual community that addresses the issues of the black community. It originated from the black American members, hence strongest in America though it has gained popularity in Africa too especially in South Africa.
The first published comments on the black twitter were in the year 2008 by blogger Anil Dash. He developed the Twitter memes such as #BlackCelebsBeLike and #GrowingUpBlack. In the year 2010, the term gained popularity after Farhad Manjo wrote an article about how black people use black twitter. It was in the sense of his observation that young black people formed tight clusters and tended to follow and retweet each other more.
The main cause of the increased attention of the Black Twitter is the fight against racism. The community protested to companies selling products from Paula Deen, who was accused of racism. This and many more incidences of condemning racism have been the reason for the growth of the community.
