One of the actual first formation of competitive gaming was Counter:Strike in 2007 which was slowly grew over the past 8 years into one of the top games involved in eSports. In 2010, League of Legends introduced it's first World Championship and the winning team got $20,000. 5 years later in 2015, the winner of the World Championship wins a million dollars. Dota 2 held it's first championships known as TI# (The International 20##). In TI1 and TI2 the prizepool for each was close to $1.5m each. TI3 awarded 4m, following year TI4 awarded 11m and TI5 had a prizepoll of over 18m. In 5 years, Dota went from a prizepool of 1million dollars to 18 million dollars and the team that won 1st place, got 6.6m dollars.

Now where do people watch competitive gaming? Well, the main source of watching competitive gaming is Twitch, which is a live streaming service for free.
