I looked for more information about videos 2 and 3:

2. The station is WNYW, the Fox affiliate in New York. The program "Good Day New York" runs from 7-9 a.m. weekdays. The current male co-anchor is Ron Corning (his partner is female) who does NOT look like the guy in the video. I can't locate the reporter, either, in their current lineup. Maybe they were both fired.

3. ESPN has a story about Brian Collins, the inexperienced sportscaster. While it wasn't a classroom training exercise, it was on a university campus TV station, which I suppose is only one step above that. He was an unpaid volunteer, a last-minute substitute for someone who didn't show, and he did have TelePrompTer problems.
