For those wondering, Stephanie Courtney (a Groundling!) plays the woman or girl in those Progressive commercials, she has for like more than a year, well since 2008. She has had multiple commercials. The character's name is Flo and I love this character! She has grown on me. She has also appeared in television commercials, such as Skittles (2008), Wienerschnitzel (2005), SC Johnson Glade products. Wikipedia even has a page on her and on the character!
