I'm not sure when you grew up, but honestly anywhere around adult age or older, frankly we just didn't have this same type of exposure to the brand. We didn't have 2, 24-hour disney only channels, on-demand entertainment, and an endless availablity to cheap-to-produce and distribute shows. Children's entire style and delivery of entertainment is different now then when we were kids.
I'd argue that the actual theme parks are fairly low on totem pole when it comes to focus and revenue. I've said for a long time, that WDW is a resort first and a theme park second. TV shows are cheap to produce and distribute being they own the networks and not pitching to a major network. TV movies like the Descendants and Teen beach movie are getting more eyeballs then if they were forced to be shown through a movie theater and look at the residual revenue they are generating—from advertising, to clothing and merchandise.
You can complain about business all you want, but the amount of resources it takes to operate a theme park for a day are staggering—Attraction, food and maintenance CM's, product supply, electricity and facilities, insurance. You can make 1 show for a fraction of the cost and run it over and over again for free all while generating new passive advertising revenue and licensing income.
Its not evil business, its math.
