StreetsOfSanFrancisco

In AOL TV's continuing countdown of the best TV shows of each decade, we're back to break down the 1970s, a decade when the cop dramas were less gritty, the families were close-knit and the sitcoms were sprinkled with serious social commentary.

Our list of the best shows of the '70s features many of the best shows of all time (here's looking at you, 'Mary Tyler Moore Show,' 'M*A*S*H' and 'Taxi'). Take a gander and let us know if you agree.
