Wonderful World of Disney celebrated the opening on March 23, 1975. Starring actor Lucie Arnaz, it was the first Walt Disney World network special, the previous one being syndicated. Ride Changes When the Walt Disney World version first opened, the post-show featured new home technology created by its then-sponsor, RCA.
