In the '70s, TV movies were one of the more interesting things the medium did -- and, according to Dan Curtis, you could approach ABC executives (like the evil-yet-competent Michael Eisner) and just describe something "fun" you wanted to do, and if you sold them on it, you were greenlighted and off you went... As the decades rolled on, however, the networks got into this "over-development" process and many smaller, unpretentious projects were ruined before they even got on the air.
In 1964, the first intended-to-be made-for-TV movie was THE KILLERS with Lee Marvin and Ronald Reagan (his last film before turning to politics) but was instead run in theatres because it was deemed "too violent" for television; it did decent business.
Aaron Spelling pioneered the 90-minute TV movie (about 75 minutes in actual running time) and they did pretty well for a while.
By the late-'80s, the TV movie genre was increasingly overtaken by the Abuser-of-the-Week pictures which soon became ubiquitous, where almost every made-for-TV entry had this two-part title and were all about abusive, rape-y, violent men who mistreated the wives and children... It became such a wall-to-wall thing for at least 20 years, that it turned into a joke (remember, women spend 80% of the consumer dollars, which is why TV, then and now, has the tone it does) and when Judith Light, a very good actress, tried to do
just one small-screen flick, MEN DON'T TELL in 1993 about an
abusive mother who mistreated her husband and kids, the women's groups went crazy, calling it "anti-woman" and accusing Light of internalized misogyny, insisting women "don't behave like men do" and placed pressure on the network to never air it again (and they didn't) despite high ratings for its first and only broadcast. So despite literally hundreds of abusive-men TV movies, you couldn't do a
single one which showed a woman in a similar light (despite the fact that women kill their offspring at a much higher rate than men do, regardless of whether the father is in the household or not).
The feminists are just so interesting...
