You'll see a single director more often on prestige (think HBO, Starz, and Showtime) and streaming shows because those shows have either completed post-production or are nearly complete by the time the show airs.

When it comes to your basic cable shows on CBS, ABC, and NBC those shows start filming about 2-3 months before airing and can take about a week and a half to film an episode. You'll see a higher quantity of directors brought in since episodes sometimes won't be complete until days before airing.
