NEW HAVEN — Coca Cola is about as American as apple pie. The original glass Coke bottle was an icon on its own until it was replaced in the U.S. in 1960 by the can. The Coca Cola logo has long been recognized by 94 percent of the global population, making it the world’s most identifiable trademark. Both the logo and the product are so thoroughly identified with the United States that for many people Coke is a symbol of America.
