Video games have grown into a $25 billion a year industry with more than 800 million regular players worldwide, and this film asks how a hobby once dismissed as a niche pastime for children became one of the biggest entertainment businesses on the planet. It traces the medium from arcade cabinets and home consoles through the rise of online multiplayer and competitive gaming, talking to developers, industry figures, and players about what changed and why. The film looks at the technology driving the growth, the culture that formed around it, and the money now flowing through publishers, tournaments, and streaming. It also weighs the persistent worries that follow gaming everywhere it goes, from addiction to violence in content, against the industry's own case for itself as art, sport, and social connection. The result is a survey of an industry that overtook film and music in revenue while much of the wider public was still arguing about whether it counted as culture at all.
