Exactly, which is often what people forget.
Look at the disgust with call of duty on Internet forums, look at call of duty sales...each year.
The majority of gamers don't sit and post on forums. People like us are a minority, in the same way people that post on a forum like avsforums and discuss calibration etc are a minority.
The average person buys a TV, puts it into vivid/dynamic and burns their retinas away with hours of TV (often not even high definition).
The average gamer walks into game/GameStop buys whatever console their friends have and buys a copy of FIFA, call of duty, Assasins creed and calls it a day.
Brilliant explanation.
