If we examine CBS, in particular, we see that top shows of the 1960s were "rural" shows like The Beverly Hillbillies (about a backwoods family living in Beverly Hills), Green Acres (urban socialites take up "farm living"), and Hee Haw (a country music variety show). Innocuous, comforting entertainment, to be sure, and still capable of bringing tens of millions to prime time, each and every night, but hardly in sync with countercultural viewers. As ratings began dropping, the whole enterprise began to sag. Commercial television was surviving the late 1960s on sheer inertia—the lasting power of attentional habits is never to be underestimated—and the fact that the backlash, such as it was, was mainly in the younger demographics, and had not reached the whole population.
