Ratings: Did ‘Extant’ finale increase season 3 chances? Also, ‘Tonight Show’ fights back

There are a number of different ratings headlines to report on when it comes to Wednesday night’s lineup, but let’s start here with a fate of “Extant,” a show that has developed a following, but is also at the same time planted firmly on the bubble for CBS.

The show drew in total a 0.7 rating in the 18-49 demographic for its final two hours of the second season, which would probably only be considered good news if the show was airing on The CW. As it is, we’re not altogether optimistic. “Under the Dome” drew better ratings and was canceled, and while this show has a streaming deal that is equally lucrative, we have to imagine that the production cost here isn’t that cheap and Halle Berry is an expensive lead for a summer series.

Still, who knows? With there being question marks at the end of season 2, maybe there’s enough in here for the network to give it a third season to tie things together.

As for the new late-night battle (which is a lighthearted one seemingly), the new “Late Show with Stephen Colbert” drew a 0.8 against “The Tonight Show Starring Jimmy Fallon,” which posted an impressive 1.2. Still, this is not a real accurate judgment on where these shows will end up; just like Colbert drew big ratings for his premiere off of curiosity over his new show, Fallon last night brought back the super-popular Justin Timberlake in what was a clear counter-programming move by NBC to ensure that not too many people stayed loyal to CBS for long.

Also worth noting is that “Big Brother” drew a 2.1 rating, further proving that the majority of those people who threaten to stop watching rarely ever do.
