I haven't watched the show, but I hear it wasn't any good anyway.
In any case, Big Beer can try, but in the end craft brew still survives and flourishes. Actually here in NY beer stores pride themselves on how much craft brew they have on their shelves and there are more and more bars that carry EXTENSIVE craft selections not to mention 4 (or is it 5 now craft breweries in Brooklyn alone.) Most restaurants and bars still only carry Big Beer, but I see a very noticeable increase in craft presence all over town. I mean you can get bigfoot in a shabby grocery that sells ginger ale and toilet paper.
Maybe in idealistic future Big Beer will be forced to become drinkable...
Actually the same trend is appearing in the Scotch world. There are now small distilleries that don't add caramel and don't chill-filter. These are becoming more sought after and sometimes even 7 year olds are as good of better than 17 year olds. Another thing they do is make kind of "coalitions" where 5 or more distillers come together, give one cask each to the cause, blend it, let it mature and meld, and produce something stunning as a result. Maybe brewers should try the same.
