Commercial insertion in nationally broadcast television

I am curious as to how an hour-long nationally televised program in the U.S., like say E.R., is actually broadcast. Does one person in New York or L.A. push a play button to start the show and all the commercials, or is there coordination between NBC and local affiliate technicians? For that matter, how is the entire programming day coordinated? What goes wrong to create “technical difficulties”? (Ignore the feed into satellite and/or cable TV for my purposes).
