Social media marketing is a new marketing trend in which different businesses have taken to social media sites to market and promote old and existing products and brands or to raise awareness of their new products. Facebook and Twitter are the two most well-known sites on which businesses market and promote themselves. More than a billion users worldwide use both sites daily; from average Joes to famous celebrities. The power of each social network is such that a single post can make or break you. Forbes estimated that in 2011, Facebook and its founder Mark Zuckerberg were worth around $50 billion due to their growing popularity. It went from a social network just for Harvard students to a global phenomenon. Twitter also has celebrities and famous personalities who are followed by millions of people. Lady Gaga, Justin Bieber and Katy Perry are the three most followed people on Twitter, with over 14 million people following them and being informed of their every move.

People in first and third world countries are aware of this, and statistics show that one in nine people on Earth is on Facebook, and Twitter has up to 500,000 users every day.
