Book excerpt: Long dismissed as ciphers, sycophants and "Stepford Wives," women characters of primetime television during the 1950s through the 1980s are overdue for this careful reassessment. From smart, savvy wives and resilient mothers (including the much-maligned June Cleaver and Donna Reed) to talented working women (long before the debut of "Mary Tyler Moore") to crimebusters and even criminals, American women on television emerge as a diverse, empowered, individualistic, and capable lot, highly worthy of emulation and appreciation.
