Back in the "Good old days," soft drinks were sweetened with cane sugar. In the 1980's, soft drink companies switched to high-fructose corn syrup, because it was cheaper. Recognizing the value of selling a genuine retro product in 2011, Pepsi has gone back to their original sugar-based formula and are using their original logos in their new Pepsi Throwback series of soft drinks. Apparently, this was test marketed in 2009 and in 2010, and was met with strong sales. Good move; it matches my original Commodore 64 system perfectly, and tastes the way it should.
