Yes. Because the marketing scope provided by a business that makes money through showing a film in a theater for a limited amount of time is perfectly comparable to the scope of a business that sells gaming products that people take home with them to use frequently.
I don't know what the word "marketing scope" means and I don't know why it's relevant to what the two of you are arguing about, but it's not that hard to see the logic behind gob's comparison.
[Ticket sales] for a successful [movie] drops over time because the people who have already [seen] it don't need to [watch] it again.
[Unit sales] for a successful [videogame console] drops over time because the people who have already [bought] it don't need to [buy] it again.
The more successful a console was at the start of its life cycle (which the Wii was, outselling the 360 and PS3 combined), the sharper the drop at the end. There's also the fact that the Wii doesn't YLoD nor RRoD, and there's no major redesign (there's no wii slim. The motion plus was a simple addon) so there's little sales to be had from people who need to replace their console.
