I want to know the answer to the following question:
When did the first public HDTV broadcast happen in the US?
All the background I'm provided with is that "The first public HDTV broadcast in the United States occurred on July 23, 1996 when the Raleigh, North Carolina television station WRAL-HD began broadcasting from the existing tower of WRAL-TV southeast of Raleigh, winning a race to be first with the HD Model Station in Washington, D.C., which began broadcasting July 31, 1996 with the callsign WHD-TV, based out of the facilities of NBC owned and operated station WRC-TV.". Is that enough to answer the question?
Answer: yes
