Ah, soft drinks.
0) Once upon a time, a wise man invented Coca-Cola and sold it to soda fountains and drug stores. It was good.
1) Then people bottled it. Everyone drank it, and it was good. Some people still liked it better from the fountain though.
2) Then people canned it. This was good, because it was easy to buy from soda machines. Some people like bottles better than cans, because they are prettier and more old fashioned Coca-Cola design. But it's the same drink as Coca-Cola in bottles, and you can mix the two without noticing any difference.
x) Some idiot changed the formula to Coke with collectible dice in it, and the company nearly died.
3) Some people on went to a slightly cheaper formula -- high fructose corn syrup instead of sugar -- but kept the flavor the same, and sold it in bigger, 20 oz. bottles. Most people said "OK". Some people preferred "parallel import" Mexican Coca-Cola in big glass bottles, made from sugar, but most people didn't care enough to pay extra.
4) Then someone came out with another new Coke. This one is based on the successful model of Red Bull for lots of weird herbal ingredients, plus it has an XTREME! logo from "Can of Whipass" energy drink, and it's the color of radiator fluid just like "Mountain Dew"! A lot of people, mostly in the 12-18 male core demographic for soft drink taste establishment, think it's super cool. Coke marketing is very excited about this.
Other previously loyal customers say "yuck" and are scrambling for some imports of the real stuff that's still being made in the little town of Paizo, Mexico. It's technically legal, for now, but Coke corporate doesn't like it much, because it's not true to the spirit of Coke corporate gets all the glory and filthy lucre that SHOULD have been in the original agreement with Coke Mexico, but was left out.
