As a member of one of television's most iconic families, Erin Moran captivated millions with her disarming smile and girl-next-door appeal. After guest stints on family-themed shows, she finally hit the big time on the beloved sitcom "Happy Days" (ABC, 1974-1984) as Joanie Cunningham, the plucky little sister of Ron Howard's Richie Cunningham. Thanks to outstanding performances by its cast, including Henry Winkler as suave greaser Fonzie, "Happy Days" attracted huge ratings during its entire run. Moran's role on the show became increasingly popular after her character fell for Chachie Arcola (Scott Baio), so much so that the network created the spin-off series "Joanie Loves Chachie" (1982-83), a short-lived but memorable sitcom about the couple's hilarious adventures as aspiring singers. After "Happy Days" wrapped, Moran took lesser parts, yet it was her role on the much-loved series that audiences forever associated her with, making the actress one of the most recognized personalities in the history of American sitcoms.
