So now we have two TWC broadcaters who have their own show but don't have an actual meteorology degree. Perfect! (Sarcasm)
That begs the Question: Why did WABC/GMA & WNBC/Today Hire them?
Couple reasons probably......
When he came to WABC in 1988 there weren't many meteorologists with degrees on tv. In fact if you look at a lot of chief meteorologists across the nation... you would be surprised at the number who didn't initially have a degree when they started out on air. In a way it makes sense considering the technological limits. With no easy way to get forecast data or reliable radar/model data.... tv stations heavily relied on third party sources for weather forecast data.
Also there simply weren't that many meteorology graduates. Today I would say its nearly impossible to start out in the business with no degree.... unless you are REALLY good looking
Sam got promoted from a station in KY to WABC. That NEVER would happen today. It's unheard of to go from a weekend wx person in market 81 to an on air personality in the #1 market in America. Once he got to WABC there really wasn't a huge need for someone with extensive weather knowledge. NYC doesn't exactly have lots of major weather events. Therefor he was able to build up an image and personality that took him to where he is now.
Al Roker and Sam Champion are a rare exception in the tv industry. I think both have worked hard and after doing weather for 30+ years I'm sure they have picked up quite a bit of knowledge. That being said I hope equal air time is dedicated to the existing degreed mets on the network
