I posted this on the previous thread but will repeat it here: Blue Bell is not a premium ice cream, never claimed to be. The secret to success has always been the add-ins, and the fact they're very generous with the add-ins, and the advertising.
I think Blue Bell was the first to do the very generous add-ins. After a couple of samples of their Cookies 'n Cream, which I think they invented, I mused that it was just like what your Mommie would fix for you if she wanted to reward you for being a good little boy or girl: a bowl of ice cream and your favorite cookies. Except the cookies were already mixed into the ice cream.
The advertising is very clever now - I love the one about the fresh faced young man on his first day on the job as a delivery man, arriving at the first customer's with nothing but empty cartons in the back of the truck. He's taken the Blue Bell slogan to heart - we eat all we can and sell the rest.
But I remember the radio commercials of 25 years ago which were, well, suggestive. They had this incredible gravelly voiced announcer who delivered his lines, well, lasciviously. I could imagine him reading his copy about Peaches and Cream Ice Cream with drool running out of the side of his mouth. Think of the late Senator Everett Dirksen of Illinois with a lascivious tone in his voice as he talked of pending legislation. You'd really want that bill to pass

I actually talked to the guy once, ca. 1978. He was just an oilfield worker from the Golden Triangle area (Beaumont/Pt. Arthur/Orange) as I recall, who happened to have been gifted with this incredible voice. I heard that he died not long after that. I heard him do some political commercials once, very strait laced delivery; but all he really ever did was the Blue Bell commercials.
