Tom Vanderbilt analyzes the state of contemporary TV. One highlight:
Today, it’s not rare for a huge portion of a show’s audience to watch it well after it originally aired. CBS, for example, recently released data showing that the viewership for its Sherlock Holmes reboot, Elementary, skyrocketed when seven days were tracked—its rating among the valuable 18- to 49-year-old demographic shot up 64 percent. (And there’s no reason to stop at seven days. Millions of hours of TV get watched beyond the one-week cutoff. Science fiction shows, it turns out, are particularly likely to be watched more than a week after they air.)
That 29 percent seems like a number that’s likely to grow, rather than to shrink, particularly as long as networks are scheduling shows with unpredictable gaps in between episodes.
