You're definitely right about the dying breed bit. Microbreweries have completely changed the beer world in the U.S. Anheuser-Busch has only survived this far because they keep buying up companies and brands rather than innovating. I can't speak for the older crowd as a millennial in America, but I have not seen traditional American beers such as Bud, Coors, Miller, Michelob, etc. at parties in awhile. Most parties and weddings I have attended have local breweries cater, hard seltzers like White Claws and Topo Chico, or some other random new craft beer.
Perhaps the Bud Light thing was Anheuser-Busch's way of trying to appeal to the younger and more diverse crowd in the hopes of bringing them back as opposed to continuing to sell to the same crowd that are dying out, primarily in rural areas, or part of the demographic that has for the first time in American history shown a decrease in population growth in the latest census.
