Playing video games has become a real job now. Players can get a lot of money. They compete, watched by thousands of fans in arenas  , with millions more following online. 40 years ago the first known competition (playing Spacewar at the US's Standford University) offered a magazine as first prize. In 2014 the world championship   for Dota 2 had the prize of almost $11 million and 10,000 fans watched live as Chinese team won the first prize. Last year also saw the first e-sports arenas open in the US and a 15,000-seater e-sports stadium   in China, the e-TV sports report by sports network ESPN and the $450,000 worth e-sports scholarship   offered by Chicago's Robert Morris University. If you're over 30, you probably don't, directly, unless you happen to be a fanatical   player of the most popular e-sports games. But your children or grandchildren do. They know the players by their gaming handles   and hope to follow their heroes into a gaming world. Who likes e-sports best, according to the passage?
Newly-born babies. Young children. Middle-aged people. Old people.
