I don't recall them prior to the past few years. We first went to WDW in 1986. The only things I'd ever seen about the place was the promo film that accompanied Snowball Express in 1971/2 (I'd love to see that again), and a magazine article about EPCOT. That made me want to go. I don't think a promo like the current ones would have prompted me to make the trip.
The old-school marketing emphasized WDW's "vacation kingdom" status. The new campaigns just scream, "PIXIE DUST! MAGIC!" over and over, and hope you know what they're talking about.
If my only impression of WDW were a modern commercial, I would assume that it was...
A) A place only for families with very young children obsessed with princesses and pirates.
B) One park with a castle icon and some attractions that don't even exist in Florida (outdoor teacups, dual-seater Space Mt., the Matterhorn).
C) A place with minimal crowds and where characters roamed freely.
I would not know about Epcot, DHS, DAK, the golf courses, mini golf, the water parks, DTD, the Boardwalk, Fort Wilderness, various watersports, convention opportunities, or anything else the "World" has to offer.
Disney is relying on getting people to visit the web site and see everything the resort encompasses, but if the marketing campaign doesn't appeal to people in the first place, why would anybody want to visit the web site?
PLUS the web site rarely works right, anyway. Somebody needs to stop drinking the Flash-is-Everything Kool-Aid and get the stupid site to WORK.
And for what it's worth, a few days ago, I heard a high-ranking officer in a certain national marketing association rip Disney's new campaign to shreds, calling it some of the worst graphic design work and most idiotic slogan he'd ever seen. I didn't say a word.
