Brace yourself for an explosion of growth in eSports in the next few years.

Competitive gaming is already growing into a lucrative industry, generating an estimated $748 million in revenue worldwide in 2015E, according to a SuperData Research report. The growth is attributed to the brands and advertisers that entered the market this year, which contributed a total of $579 million in sponsorships and advertising.

SuperData analysts forecast the explosive growth in the eSports industry will become a year-on-year phenomenon.

Stephanie Llamas, director of research and consumer insights at SuperData, said the market will grow to over $1.9 billion by 2018, driven mainly by the U.S. and Europe, which are expected to rapidly invest in the space as the Asian market approaches stagnation.
