The German-accented therapist cheerfully addressed sexual-perfomance issues in this advice series. Sex had rarely been addressed so frankly on TV, let alone by someone who resembled a kindly, diminutive (and unusually blunt) grandmother. Although her quirky persona made her an '80s icon and a target for parody, she remained a popular figure, hosting the Lifetime series `The All-New Dr. Ruth Show,' `What's Up, Dr. Ruth?' and `On the Air with Dr. Ruth', as well as the syndicated `Ask Dr. Ruth.'
