[{"role": "system", "content": "Dr Pepper is a carbonated soft drink marketed as having a unique flavor. The drink was created in the 1880s by pharmacist Charles Alderton in Waco, Texas and first served around 1885. Dr Pepper was first nationally marketed in the United States in 1904, and is now also sold in Europe, Asia, Canada, Mexico, Australia, and South America, as well as New Zealand and South Africa as an imported good. Variants include a version without high fructose corn syrup, Diet Dr Pepper, as well as a line of additional flavors, first introduced in the 2000s. The U.S. Patent Office recognizes December 1, 1885, as the first time Dr Pepper was served. It was introduced nationally in the United States at the 1904 Louisiana Purchase Exposition as a new kind of soda pop, made with 23 flavors. Its introduction in 1885 preceded the introduction of Coca-Cola by one year. It was formulated by Brooklyn-born pharmacist Charles Alderton in Morrison's Old Corner Drug Store in Waco, Texas. To test his new drink, he first offered it to store owner Wade Morrison, who also found it to his liking. Patrons at Morrison's soda fountain soon learned of Alderton's new drink and began ordering a \"Waco\". Alderton gave the formula to Morrison, who named it Dr. Pepper (later stylized as \"Dr Pepper\").\n"}, {"role": "assistant", "content": "Coke? Pepsi? Neither. Dr. Pepper is the real stuff! This stuff has been around since the 1880s, served first in 1885...before both Coke AND Pepsi. It should be the real #1."}, {"role": "user", "content": "Definitely Coke, Diet Coke in fact. Can not get into Dr. Pepper though, but everyone else I know loves it."}, {"role": "assistant", "content": "Okay, I'll respect the difference in taste. I'll say one thing--it was invented by a pharmacist in Waco, Texas. When it was introduced to the public at Morrison's soda fountain, a store owner who really liked the drink, his guests kept asking for a \"Waco\"... Glad that name didn't stick."}, {"role": "user", "content": "Yeah, that's kinda weird. Now, is Dr. Pepper a Coke product or a Pepsi product?"}, {"role": "assistant", "content": "It's neither; it's its own product. Technically fully introduced nationally in the US at the Louisiana Purchase Expedition in 1904 as this kind of \"new soda pop,\" made with 23 flavors. They still use that tagline today, actually, with a \"23\" on their can at times."}, {"role": "user", "content": "I didn't know that, interesting. Where is the factory that it is made at located today?"}, {"role": "assistant", "content": "They have many factories today, all over. I just love the idea that it was called \"Dr. Pepper\" because it was invented by a pharmacist, of all people."}, {"role": "user", "content": "Has the formula always remained the same?"}]
