For cable and streaming services, yes. For broadcast series, not so much. Some shows generate a considerable amount of buzz before they premiere, while others tend to fly under the radar. A number
of new series with strong pre-season buzz have become instant successes (such as "The Walking Dead" and "This is Us"), while others have just as quickly flopped (see "Heroes Reborn" and "The Bastard
Executioner"). Many others received little pre-season notice and yet became long-running hits (e.g., "NCIS" and "Grey's Anatomy").
