Barbara Walters is known for being one of the most seasoned interviewers in broadcast journalism, but when she entered the field more than 50 years ago, it was a man's world. As Walters worked to make a name for herself, she discovered what an uphill battle it was for female journalists in the male-dominated industry. She shares her brutally honest experiences in the above video from "Oprah's Master Class."

For example, Walters says, it's no secret that she "had difficulty" with fellow journalist Peter Jennings. Though she has incredible respect for the late broadcaster -- "He could write like a dream; he was such a superb newsman." -- Walters says she still struggled with her treatment at the news desk.

"He would cut me off, he would never say 'thank you' or 'that's interesting,'" she says. "We all sort of took it for granted. I don't want to put Peter down; it's the way it was thought of then."
