When Pop Became Soda
A terminology survey: When referring to soft drinks, do you use the term pop. soda, or soda pop?
When I was growing up in Phoenix, the common term was "pop." Soda was a drink with ice cream that was served at a counter in the drugstore. As more and more refugees from eastern and midwestern winters arrived, "pop" was heard less often. I rarely hear it now.
Perhaps it was replaced by "latte."
