The domestic farce may be the most American of comic concepts. The moment that Burns and Allen admitted to their radio audience that they were a married couple, a tradition of laughter on the home front began. Groundbreaking television sitcoms like "The Goldbergs," "I Love Lucy," "The Honeymooners," "The Dick Van Dyke Show," "All in the Family," "The Cosby Show," "Roseanne," "Seinfeld" and "The Simpsons" reflect the ongoing changes at home and in the workplace. Sitcoms continue to be a consistent and hilarious barometer of American gender roles and attitudes toward racism and politics.
