What's tough, though, for women, is that very few, if any, would have any chance of being on TV if they weren't attractive. Those that stay around awhile (like Oliver, Storm, Tafoya, Visser, etc.) generally have gained enough credibility that they will remain on the air even after their looks begin to fade.
It's a mixed bag, though. Many of them did do things to make themselves appealing on TV, and certainly enjoyed the accolades they received. Accordingly, they are subject to criticism when their looks fade.
That's why they are better off just being who they are from the get-go, and not trying to dress provocatively, etc.
I don't know what the deal is with Oliver. It's strange. She's been around a while and was always attractive. The last 2 years, it seems, she looks very different. It's odd. (Lesley Visser, even moreso). What I really don't get is the hair, though. I asked my little girl during the NFC championship game what she thought of Oliver's hair. "It's goopy," she said.
Erin Andrews is the one that I think is going to really have a hard fall. She isn't very good at her job (unlike Oliver, Tafoya, etc.), and has the kind of face that may not age very well.
