Anheuser-Busch , which brews Budweiser, Busch and Michelob, is the longtime U.S. market leader with just under half of all U.S. beer sales. Miller holds 18.7 percent of the market and Coors 11 percent, according to Michael Scherer, who teaches management at Harvard's Kennedy School of Government. The rest of the market is shared by imports and microbrewed beers.

The proposed merger would give Anheuser-Busch and the new MillerCoors joint venture control over nearly 80 percent of the U.S. beer market.

The deal could hurt Pabst Brewing Co, which has 3.38 percent of the U.S. beer market, since Miller brews most of Pabst's beer and could opt to shut down that plant, said Scherer. "This could put them in a very squeezed position," he said.

Hey I like PBR and other 'imports', I see this as a risk to the small guys...
