The photographer has been on TV (so they must be good).
Photographers who have been on TV are proud of the fact, but they also use this “as seen on TV” as a way to make themselves look important or significant in the eyes of others.
The fact a photographer has been on TV is no guarantee that you’ll get better photographs or have a greater experience than working with a photographer who has not.
In the end, judge the photographer’s work, evaluate the costs, and choose the photographer you feel is best able to suit your individual needs.
