SODA vs. POP

Ok, call me a giant dork, but I think it is so interesting to learn about cultural differences within in the US. Maybe my sociology major has something to do with it, or the fact that I grew up in Wisconsin and have since lived in North Carolina (for school), Atlanta, and DC.

So at work today one of our advertisers had a blurb on their landing page about regional differences and 'carbonated soft drinks' -- anyways, take a look:

• Soda - "Prevalent in the Northeast, greater Miami, the area in Missouri and Illinois surrounding St. Louis and parts of northern California"
• Pop - "Dominates the Northwest, Great Plains and Midwest"
• Coke - "Predominates throughout the South, New Mexico, Central Indiana and in a few other single counties in Nevada, Utah and Wyoming" (Source )

I definitely say "soda" (contrary to the area where I grew up) -- but SB says "coke." What do you say??
