'America's Got Talent' -- Cheesy Sponsor Stands By Howard Stern

PIZZA FEARS NO ONE ... especially not a group of angry Howard Stern-hating parents -- which is why Pizza Hut is refusing to pull its advertisements from the controversial new season of "America's Got Talent."

A rep for the Pizza company tells TMZ, Pizza Hut has no plans to remove its ads from the show -- despite the Parents Television Council clamoring for sponsors to yank their support over the show's new judge ... shock jock Howard Stern.

The rep tells us, "Pizza Hut strives to maintain the highest standards of quality and excellence in our communications to the public. Our advertisements are no exception, and are designed to draw attention to our products and appeal to a broad audience."

The rep adds, "Unfortunately, we may not always success in generating a positive impact on every guest, and we apologize if our methods offend some."
