Is Pepsi a Coca-Cola product

No-one really knows. Here's the order.

First: Dr-Pepper (December 1, 1885)

Second: Coca-Cola (1886)

Third: Pepsi (Ten years later after Coke)

I have tried both coke and pepsi. Coke is however kind of sweet to me. And pepsi is ok. Really you can't find the difference of coke's and pepsi's tastes. They both actually taste the same. So I wouldn't really say pepsi copied coke.
