"A coffee shop there, in Boston, Massachusetts, combined a milk shake with coffee and called it "frappuccino". When Starbucks bought the shop, the Coffee Connection, it bought the trademarked name."
"Many of Starbucks' competitors, in the United States, in the Philippines and elsewhere, have begun offering drinks similar to the popular and trademarked frappuccino and called them "frappe" with or without the accent, some which do not include any coffee"
A "frappe" was originally(?) the Boston/New England term for what others normally call a milk shake. In Boston, some took "milk shake" to mean just flavored milk. You don't see the frappe term used in this context much any longer but it was still fairly common when the Coffee Connection chain was around.
