Factual error: During Howard's "Thank You" speech to New York he gives NYC the gift of a live performance by AC/DC. The year was 1985. As the band takes the stage and launches into "You Shook Me All Night" we see Phil Rudd on drums. Rudd had quit AC/DC two years earlier and was replaced by Simon Wright. (Rudd returned in 1994, hence being part of the band when the scene was filmed).
Factual error: In the scene where Howard arrives at WNBC, his moustache is gone and his hair is long. The first few years at WNBC, he still had short hair and the moustache. Also his original air shift was from 4PM-8PM, later changed to 3PM-7PM to accommodate for the Knicks and Rangers broadcasts.
