Grandmother of Texas Sugars (1981) This pair of television commercials produced by the Dallas-based TracyLocke Company celebrates the 150th anniversary of the Imperial Sugar Company. “Whether you bake a little or a lot,” its twangy jingle sings, “use the sugar the pros use.” Though sugar has not been refined at the company's original plant since 2003, Imperial's headquarters remains in Sugar Land, making it the oldest extant business in Texas.
