FWIW, I drink beer or ale occasionally with almost no consumption of hard liquor. These days generally I prefer red wine over beer. I'm pretty moderate in my consumption of both.
With that being said, here are my thoughts:
Bud is bland tasting. IMHO, it is predictably and consistently dull as compared to the other beers in market. As a massive consumer group, the market seems to agree.
I stopped drinking Bud/Michelob 35 yrs ago.. Beers from EU took over my re-fridge and were much better tasting to me. Becks, St. Pauli Girl..and a few others won me over. I recognize that I was not in a majority, though. But I also observed over time that a sizable group migrated away from Bud and USA and NA beers.
Fast fwd to the mid-' 90s:
Beer tastes changed. In essence what has happened (over the last 20 yrs) to the beer/ale market is the quality of the competition has come WAY up. Micro-brews sprung up upon our shores Anheuser-Busch as a company didn't do enough about research and put out premium micro-beers. They were rigid and ignored the trend at their peril. (Think GM)
Bud's new mother company, (InBev) has seen Bud's loss of market share and are changing their product line (though aren't changing Bud beer's recipe for brewing).
BTW, new in the last yr...new additions to their line. You should taste their line premium ($$$) brew and their micro-brews and lovely EU beers. InBev owns a slew of big EU top-selling brews.. (Stella Artois...and luscious Belgian beers).
IMHO, beer drinkers who are objective and pay attention and selective about the taste seem to agree. However, some folks still just drink it out of habit or availability...cost or whatever.
For me, my taste is Sierra Nevada Pale Ale and quite a few of Sam Adams brews - now and then a Yeungling or two. I'm pleased they're made in USA.
That's just me.
