Established as a single resort by Walt Disney in Anaheim in 1955, Disneyland has grown to become the largest employer in Orange County. Disneyland Resort also is California's number one tourist resort destination. The California Senate Rules Committee honors the memory of Walt Disney and his lasting legacy of quality family entertainment by proclaiming Disneyland Day on June 1st.
