ESports: ephemeral phenomenon or new mass movement?

Recently, a new phenomena has emerged in our society: Esport. This is actually the video game at a competitive level. This means that players are professionals and they are paid to play. 
The eSports has particularly developed during the last 3 years and has become a major phenomenon. Games that have contributed to the success and reputation of the League of Legends eSports are, Dota or StarCraft. 

But is eSports is a movment that will fade quickly or is it a new mass movement? I personally think the Esport will exist for a long time and will know its peak in 5 to 10 years. 
The first reason that I think is simply the number of people who follow him. For example, the World Final game League Of Legends in 2013 was attended by over 32 million viewers around the world. This year the figure increased further, the final taking place even in a stadium that was used for the World Cup Soccer! 

In a society where 50% of people are gamers, it seems doubtful to see such a phenomenon fade. 
The Esport is also a very professional environment. More and more major brands like Samsung or Pringles have realized the potential of this discipline and began to sponsor teams, tournaments for sums amounting to several million dollars. The Esport has become a new grail for investors, finding in this trend, profitability ensured for the number of people affected by these video games. 

Finally, critics argue that this is not a virtual world and have nothing to do with reality and "real" life. Yet outside of the game, the Esport is unifying allowing millions of people to meet, united by a common passion. In the countries of Europe and North America, more and more events are created, attracting an average of several thousand spectators and themed video games at a competitive level. 

So I think esport a very bright future, and for now it is only the foundation of a movement that will become more and more elaborate over time and the development of new technologies.
