Disney unveiled the new World of Color TV spot on the official DisneyParks Blog today, but along with it they made special mention of the new California Adventure logo.
Interestingly, the park's name has also changed. It's no longer Disney's California Adventure, but instead just Disney California Adventure.
I kind of like the logo. It definitely helps set the tone for the park's new direction — it's very reminiscent of early Disney cartoons, which is a perfect for Paradise Pier and the era that will encompass Buena Vista Street and Hollywoodland.
The name change is an interesting move for Disney. The change is subtle, but allows Disney to have the thematic freedom they need with this park. The possesive "Disney's" seemed to imply it was Disney's park based on California; which would leave one to expect a park based on a historical California, which is something that was never accomplished at DCA. The new name, lacking the possesive 's, now implies that it's a Disney-themed California experience. With the infusion of Disney characters and stories throughout the park, this name change makes perfect sense.
Here's a look at the new logo and a look at the previous two official logos.
