As I write this, the death of Mary Tyler Moore was announced within the last hour. While MTM is rightfully lauded for her role as a single career woman, Diahann Carroll's role in "Julia" broke more ground on more fronts. Ms. Carroll depicted a black woman trying to balance a job as a nurse with raising a 6-year-old son after her husband in the Vietnam War. Add the fact that this series debuted in 1968, there were a LOT of glass ceilings shattered when NBC began airing it and even though it apparently drew criticism, the network stuck with it for three years until Ms. Carroll had had enough.
On top of that, it was a good show, a "dramedy" that was presented in understated fashion without laugh track but with a nice chemistry between the core cast of Ms. Carroll, Marc Copage as her son and old pros Lloyd Nolan and Lurene Tuttle as her doctor boss and charge nurse, respectively. I rate "Julia" a 9 because it could be a little flat at times, but it deserves far, far more attention than it receives even today.
