In the spring of 1973, CBS became enmeshed in controversy when it refused to air a "racy" episode of "The New Dick Van Dyke Show."
The offensive subject? A 12-year-old girl walks in on her parents while they are having sex in the middle of the day. The incident occurs off-screen, neither of the TV parents (Van Dyke and Hope Lange) appears sans clothing, and they discuss the incident with their daughter. Still, CBS decided the episode was "inappropriate," arguing that America wasn't ready for such frank depiction of sexual material.
Thirty-two years later, CBS aired an episode of "Two and a Half Men" in which 10-year-old Jake (Angus T. Jones) walks into his uncle's bedroom to find him in bed with their crazy neighbor. Uncle Charlie (Charlie Sheen) explains that his one-nighter was a mistake, "because I had sex with someone who knows how to disable the alarm system."
Such scenes have inspired many viewers to call for a return to the standards of 1973. These critics are right that television portrays sex "inaccurately" -- but it does the same when portraying violence, body image, family relations, romance, and just about every other topic. Family experts have long insisted that parents watch TV with their kids for just this reason: to correct, explain, and evaluate what kids see. Since it is no secret that TV influences children, and not always positively, why has the Kaiser Family Foundation's report concerning sex on TV become a hot topic?
