Coke Confusion

I love soda, but hate the hundreds of calories that come with each serving. My favorite brand is Coke and recently Coke has released a bunch of different varieties of its brand. To accompany Coca-Cola Classic and Diet Coke, the company released C2, Diet Coke with Splenda, and Coke Zero. Coke Zero confused me the most because it a zero calorie Coke varient and I just thought it was Diet Coke. So here's the lowdown on some of the Coke products:

• Coca-Cola Classic: The original formula, full-calorie Coke. The "Classic" part was added to the name after the unsuccessful launch of a new Coke formula in 1985, unofficially dubbed "New Coke."
• Diet Coke: Introduced in 1982, Diet Coke is a zero-calorie Coke variation. It contains aspartame, a sugar substitute. Diet Coke doesn't use the same flavor formula of Coca-Cola Classic. Instead, it uses an entirely different formula and as a result, it has a different taste.
• C2: Released in the US in 2004, it is a reduced-calorie version of Coca-Cola Classic. It has half the calories of a single serving of Coca-Cola Classic. It's basically Coca-Cola Classic with half high fructose corn syrup and half sugar substitutes. It's not doing very well in the market.
• Diet Coke Sweetened With Splenda: Released in 2005, it's the Diet Coke flavor formula that is sweetened with a different sugar substitute. In this case, it's Splenda. According to the Splenda company, its zero-calorie substitute tastes more like sugar than aspartame.
• Coke Zero: Also introduced in 2005, it's also a calorie-free Coke varient. However, unlike Diet Coke, Coke Zero uses the same flavor formula as Coca-Cola Classic. It uses a sugar substitute mix of aspartame and acesulfame potassium.
  

I find Coke Zero the best calorie-free Coke varient. On the other hand, Diet Coke and Diet Coke with Splenda tastes bland and watery. I've never tried C2, but apparently not many people have either.

I hope this clears up the confusion.
