Are computer games, in general, a "horizontal" or "vertical" product? By horizontal I mean they are marketed towards the "masses." While a vertical push would be towards a particular, narrowly defined segment of said "masses."
Since computer games require a computer (or a console), they are already a segment of humanity, but I don't think that alone causes them to qualify as a vertical market. PCs and consoles are proliferating, and the game developers consider all such people their market. So this would mean that the games have to be considered horizontal.
I have more to say, but I'm not writing an article here...I'm trying to start a discussion. =)
