The fact that 1970s sitcom "All in the Family" was "a huge hit, the No. 1 show on television for more than half its run... may also have been a high-water mark for television in terms of how much impact a single series can have in shaping American culture," writes Neil Genzlinger. His review of the just-released boxed set of the iconic show also takes a sharp look at a bygone era's TV environment versus today's. "All in the Family"'s nine-season run "represents one of the last times that the best show on TV was also the most popular show on TV," writes Genzlinger. "Today it often seems as if the opposite is true. Some of the best shows of our age — 'Mad Men,' 'Breaking Bad' — have relatively small audiences."
