In Jersey City, where I live, the bars have a great selection of microbrews. All American companies that make outstanding beers: Lagunitas, flying fish, flying dog, Brooklyn brewery, just to name a few. It is actually hard to find a bar that has bud, coors or miller.
While I love the microbrews, sometimes I just want inexpensive
Beer while I am out with my friends for the night or watching a game. That is where bud, miller and coors come in. If I am in the mood to have a few beers and don't want to kill my wallet or my stomach I reach for those. If I just want to relax with one really good tasting beer I go American microbrew.
I also think the proliferation of beer bars and the availability of these great microbrews has hurt the big 3.
On a side note, when I was in Ireland every pub had coors light on tap and the bartenders told me it is very popular in Ireland.
