What significant deal did Walt Disney broker with ABC?

The significant deal that Walt Disney brokered with ABC was to finance his theme park, Disneyland. In the early 1950s, Disneyland was a groundbreaking concept, but Disney faced financial challenges in bringing it to life. By entering into a partnership with ABC, he secured the necessary funds to build the park. In return, ABC received broadcast rights for a television show that promoted Disneyland. This collaboration was instrumental not only in the park's successful launch in 1955 but also helped establish Disney as a major player in both television and theme park entertainment industries.

The other options, while related to Disney's vast impact on the media and entertainment landscape, do not accurately reflect the nature of the deal with ABC. Disney was well-known for his animated features and franchises, but his partnership with ABC was primarily focused on the financing of Disneyland rather than on creating movies, producing short animations, or launching subscription services.
