The "video games are bigger than Hollywood" claims are at best wrong, and actually bullshit. Those claims are made from comparing the entirety of the Games Industry to the US box office, which is only Hollywood's first pass at profit making.
Consider second run theaters, on demand and rental, physical purchase, digital purchase, broadcast rights, and THEN consider licensing for clothing, toys, and everything else.
Games are nowhere near the size of Hollywood. They just don't bother correcting people who make those claims.
