Once upon a time in TV land, there were just a handful of networks, and the programming calendar was intently, and inescapably, seasonal. There was a time for pilots and premieres, and a month for finales. Summer was summer, a sacrosanct time when everybody did reruns. And sweeps weeks? I’m not sure how to explain that anachronism. Of course, today is very different—less predictable, much more chaotic. Shows come and go, and while the programming slate is sometimes foretold at some comic book convention, more likely you’re unexpectedly discovering whether your favorite show is getting renewed or canceled while mindlessly scrolling Twitter.
