Only seven products used the Pillsbury name in 1950, but the company began adding to its product line. The early 1950s brought the acquisition of Ballard & Ballard Company and the beginning of packaged biscuit dough, which would become one of the company's most important and profitable product lines in later decades. The company began advertising heavily on television. In 1957, Pillsbury commissioned a TV commercial jingle (from its advertising agency Leo Burnett) with the main lyrics "Nothin' says lovin/Like somethin' from the oven/And Pillsbury says it best". The jingle became a well-known signature of the company and was used, with modifications, for at least 20 years.
