Social media is the collective of online communications channels dedicated to community-based input, interaction, content-sharing and collaboration.Websites and applications dedicated to forums, micro-blogging, social networking, social bookmarking, social curation, and wikis are among the different types of social media.

social media sites are computer-mediated technologies that facilitate the creation and sharing of information, ideas, career interests and other forms of expression via virtual communities and networks. The variety of stand-alone and built-in social media services currently available introduces challenges of definition.

1) Orkut

FOUNDER: Orkut Buyukkokten
LAUNCHED: January 2004
PRESENT STATUS: Shut in September 2014

Started by Buyukkokten, a Turkish engineer at Google, Orkut was the result of the search giant’s failure to buy Friendster. Orkut, while not much of a success in the US, proved big in Brazil and India, its two key markets. But in September 2010, Facebook, which debuted two weeks after Orkut’s launch, went past Orkut in terms of number of users in India, and a year later, did the same in Brazil.

Orkut had 19 million users in India and 34 million in Brazil, when it lost the top spot to Facebook. Google fi nally shut Orkut on September 30, 2014.

2)  MySpace

It may be hard to imagine how big MySpace was. In 2006, it beat Yahoo and Google to become the largest website in the US by page views. Rupert Murdoch’s News Corp had bought it the previous year for $580 million. Its valuation shot up to a staggering $12 billion in 2007, when it had 300 million users.

But it was all downhill for the site from there as Facebook closed the gap with MySpace and became the largest social networking site. News Corp sold MySpace in June 2011 for just $35 million.

It was sold to a Malaysian internet company in 2009 reportedly for $100 million. At the time of the sale, Friendster had around 75 million users in Asia. Friendster turn it into an online gaming platform in 2011 and was disabled four years later.
