a writeup about Charlie's Angels, TV Guide 1979
Shelley's casting on Charlie's Angels in 1979 generated so much publicity for the TV series. Not only did the show get a new, updated and glamorous look, it got the audience interested in how the new Angel would work beside veteran Angels Jaclyn Smith and Cheryl Ladd. The series experienced a major slump in the past season, finishing at no. 12 over-all in the Nielsen ratings (It was no. 5 the first season, no. 4 the second season). Shelley's debut episode "Love Boat Angels" finished at the top of the ratings for the week it first aired.
