"When women get into television, they dye their hair blonde."
Something about TV and blondness, apparently. But what?
When I was a teenager in the 1960s, and there were no women newsreaders on TV or radio, a high school teacher explained to the class that women could not be hired for these positions because their high-pitched voices simply did not work properly in broadcasting. A male voice was — to use a contemporary employment law term — a bona fide occupational qualification. He said it with utmost seriousness and authority, like it was science, and though it made me feel angry and rebellious, I believed him. Something about the technical equipment, which is another thing only the males can handle.
