> if they've bought into it being wholesome and "valuable"

I don't know if that's a representative opinion. Ads are ads. Having the host read copy doesn't tell me anything about whether the product works for me.

There's a scene in Fight Club where Brad Pitt gestures at a bus stop men's underwear ad with a chiseled model on it and says dismissively "Is that what real men look like?"

Moments later, he is shirtless, with a perfectly chiseled body (that fitness trainers will tell you is impossible to keep year-round) fighting waiters and parking lot attendants.

The movie itself is an ad. It would never have sold well if two schlubby middle-aged actors had been cast to play it.
