In the latter part of the 20th century, the first computer games were created with one purpose: to entertain their players. It was intended to allow players to escape their daily routines and give them access to fantasy worlds. Games began competing for players’ attention against other forms of entertainment such as films, theatre performances, circuses and zoos.

Planet Earth began the next millennium as a nation of more than 6 billion. The forecast for 2023 is that it will have 8 billion. Assuming that computer gaming will end up being an alternative to job work, and instead become part of it, 4 billion people will play video games each year.
