I prefer doctor pepper to other soda drinks. Dr Pepper is a carbonated soft drink 
Oh yes! Dr. Pepper is my favorite soda of all time. Nothing even comes close.
Its been around for a while, first created in 1880's by a pharmacist Charles Alderton in Waco, Texas
It's interesting to know it was so old. It was made with cane sugar back then which I bet was way better.
It would have been market 1904  when everyone in the Us got a hold of one as it was first marketed then.
