Debbie Drake was the first woman to have a daily exercise show on TV. The show’s intended audience was housewives, but as the Physical Culture Study blog notes, it was more popular with men:
Debbie Drake’s The Debbie Drake Show went national in 1961 and warned female viewers about the consequences of an unhappy marriage if they did not take care of their bodies. Drake’s media outreach included a newspaper column titled “Date with Debbie,” exercise albums and books, and a Barbie-like doll sold by Sears in the early 60s. Alluring and wearing a tight-fitting leotard that emphasized her incredible figure, Drake was reported as being more distracting than encouraging as a fitness instructor. No doubt this was aided by the fact that many stations broadcast her show at off hours, guaranteeing larger numbers of male viewers who appreciated her sexual appeal.
