At least one lingering mystery for new NBC drama "Manifest" has been solved: The show has been picked up for a full season.

NBC announced on Thursday that it had picked up an additional three episodes of the freshman series, bringing its total season one episode count to 16. As Variety reports, a typical broadcast network season-length pickup is usually between 22 and 24 episodes, but that model has become increasingly less common in recent years -- especially with prestigious dramas, like fellow NBC series "This Is Us," which clocks in at 18 episodes per season.

Though "Manifest" hasn't enjoyed the same accolades as its sister series, it's still been quite popular for the network, scoring an average of 17.2 million viewers per episode, based on in Live+7 numbers. That's just a shade behind the series premiere's excellent debut, which pulled in more than 18 million pairs of eyeballs in L+7 viewings.

In today's increasingly cluttered TV landscape, numbers like those are big news. It makes sense that NBC wants to keep unspooling the show's secrets -- and keep drawing in viewers -- for as long as possible.

In addition to "Manifest," other freshman series to receive full-season pickups include "New Amsterdam" (NBC), "Single Parents" (ABC), and "FBI" (CBS). We'll see how many of them stick around for season two.
