In the 1960's, sitcoms finally came into their own, having been minor players in television up to that point. And few sitcoms were ever so perfectly encapsulated as was That Girl, which featured a beautiful, perky, and chaste young woman, Marlo Thomas, her handsome and equally chaste boyfriend/fiance, Ted Bessell, a catchy theme song, and a gimmicky opening where at the end of each introductory sequence, dialogue ended with 'That Girl', the speaker motioning toward Marlo Thomas. From the IMDb:
To many of us born in the fifties and becoming teen-age girls by the mid-late 60's, THAT GIRL was THE show to tune in to and see the hair and fashions and enjoy the comedy. The chemistry between the two actors is just great. The show was well casted and polished. My best friend in the 60's and I never missed an episode on Tuesday nights. Hollywood did not spoil Marlo, as she went on to author several wonderful books and of course, carry on her father's work for St.Jude Hospital for the children. This was the first show to feature an independent woman who wanted to make it on her own without having to rely on her parents or her boyfriend. The humor was very broad and Ann, even though she was independent, often found herself in some very awkward situations. I especially loved the last season in which we saw Ann's relationship with Donald really blossom as they finally became engaged. Too bad it ended before they walked down the aisle.
I used to have to suffer through this series in my teens, but in retrospect I have to admit that it was a really good program, one definitely worth your while to watch. YouTube features many if not all episodes, and all are available on Hulu. I've embedded a couple below, in case you are interested in seeing what grrrrrl power looked like 50+ years ago.
