In 1925, when The New Yorker first appeared, televisions existed only in the lab. A decade or so later, they entered homes. At first, they were shy, and hid themselves inside hulking wooden cabinets. Then, in the sixties, they got more adventurous. They grew taller, thinner, and flashier; eventually, they colonized the rest of the world. Today, pretty much anything with a screen can be a television. Meanwhile, TV has become a way of seeing, a sensibility, a genre—a method, in short, for telling stories and organizing ideas. And many of these visual stories can be viewed anywhere, at any time.
