B&C partnered with Inscape, the TV measurement company with glass-level data from a panel of more than 7.7 smart TVs and device, to reveal viewership trends around late-night talk shows. We examined ABC's Jimmy Kimmel Live, NBC's The Tonight Show Starring Jimmy Fallon and CBS' The Late Show With Stephen Colbert, as well as two TBS shows: Conan and Full Frontal With Samantha Bee (the latter, unlike the others, is a weekly show) for the full month of January. (Full Frontal also arguably falls outside of the late-night daypart, as traditionally defined, but most TV critics and industry observers seem to group it in the late-night talk genre, so we’re including it here.)
Overall, most people are watching these shows live — which makes sense because they offer timely commentary on the day's news and pop culture. The one exception is Full Frontal — it has more DVR viewership than the other shows.
There's also a good amount of network loyalty going on: viewers tend to consume programs on the same network that the late-night show is broadcast. Also interesting is that when it comes to ABC, NBC and CBS, there’s some cross-viewing of late-night shows: people who tend to watch one are likely to watch additional late-night series.
TBS-viewing households are more likely to watch sitcoms on TBS or other channels such as Comedy Central and FX, while ABC/CBS/NBC-viewing households often check out dramas and reality shows on the broadcast networks.
A note about how to read the graphs below: for the show and network charts, the index describes the affinity with the network or show — the higher the index, the more affinity. The percent of TVs means the number of TVs that watched the show that also watched that network or show.
