In 1972, Harrah's Entertainment became the first gaming company to be listed on the New York Stock Exchange.
The Nevada State Legislature established specific criteria for inclusion in The Black Book and lowered the sports betting tax, allowing for the proliferation of legalized Nevada-based sports books.
