That's a little bit tautological and a little bit misleading; tautological because widely-known beers have nationwide production and distribution and so of course they're produced by big companies, and misleading because unlike unlike self-care products like Axe and Dove, the different beer "brands" owned by major brewing firms tend to be run out of different breweries with different practices; they're different products, just with shared financing.

And, obviously, within any one local market, there will be far more better-known regional brands, often not owned by any big corporation.

Most have merged recently and are global. Give it ten years and bet you’ll find the breweries have consolidated somewhat.

That is the exact opposite of what has been happening in recent years. Bigger independent breweries get bought out but more smaller ones take their place.

AB InBev has a 28% global market share for beer. Interestingly as beer consumption shifts towards craft beers they are buying up a lot of the more well known and successful ones.

They can't do it fast enough though, or at least I hope, to make a legitimate entry into the craft market. I think among people into craft beer it's well known that AB InBev owns Goose, Michelob, Shocktop, Corona, Stella, Modelo. Elysian is less-known as an AB-InBev brand but it's becoming more well known. They have to know that their business practices taints any brand that they buy out at this point, it's just a matter of milking popular high-quality brands as long as they can before public reception catches on
