Book excerpt: Our understanding of history is often mediated by popular culture, and television series set in the past have provided some of our most indelible images of previous times. Yet such historical television programs always reveal just as much about the era in which they are produced as the era in which they are set; there are few more quintessentially late-90s shows than That ‘70s Show, for example. From Memory to History takes readers on a journey through over fifty years of historical dramas and sitcoms that were set in earlier decades of the twentieth century. Along the way, it explores how comedies like M*A*S*H and Hogan’s Heroes offered veiled commentary on the Vietnam War, how dramas ranging like Mad Men echoed current economic concerns, and how The Americans and Halt and Catch Fire used the Cold War and the rise of the internet to reflect upon the present day. Cultural critic Jim Cullen is lively, informative, and incisive, and this book will help readers look at past times, present times, and prime time in a new light.
