Lasting in its original run from 1970 to 1977, Moore played the character of Mary Richards, who worked as an associate producer for a Minneapolis television station. With the series garnering 29 Emmys in total, Moore herself won seven Emmy awards over the course of her career in show business, which includes five for Outstanding Lead Actress in a Comedy series.

In addition to her work on camera, she also established her namesake company, MTM Enterprises with her husband at the time, Grant Tinkler producing the series.

In addition to the show and its various spin-offs, the company produced shows and television movies well into the 1990's.

She also found work in feature films, such as 1967’s “Thoroughly Modern Millie,” opposite Julie Andrews. She was also nominated for an Oscar in 1981 for "Ordinary People." In addition to her work within the entertainment industry, she was also a spokesperson for the Juvenile Diabetes Research Foundation.
