As for early morning newscast. I can understand if New York, Las Vegas, or Chicago can start their news at 3AM. Remember New York, Chicago, and Las Vegas are considered to be a 24/7 or 5 city. New York City slogan. City that never sleeps. In Chicago, people commute far away to work far away as Milwaukee, South Bend, and Rockford IL. In Las Vegas, people party until dawn. Also, casinos and nightclubs are up all day and night. As for L.A. I've only could think of two places that open very late. The Sunset Strip and Hollywood. In San Francisco, the city shuts down at 2AM. Have you ever try to go out to night clubs in San Francisco. They shut the bars/clubs at 2AM and the only place that opens later is the End Up in S.O.M.A.
