Why do women dominate in PR?

Ann Friedman has noticed something peculiar about the pitches she gets from public relations professionals: "The job of producing hard-hitting, democracy-protecting journalism is still, statistically speaking, the domain of men. Most newsrooms are more than 60 percent men, whereas 73 to 85 percent of PR professionals are women, depending on how you tally it." Friedman attributes the disparity to the lingering "stereotype that public relations is not a serious job."
