One month after launching the CBS Brand Channel on YouTube, CBS’s daily feed of news, sports and entertainment clips have become some of the most widely viewed content on the site.

CBS has uploaded more than 300 clips that have a total of 29.2 million views on YouTube, averaging 857,000 views per day, since the service launched on October 18. CBS also has three of the top 25 most viewed videos this month (Nov.1–17), including clips from CBS’s Tuesday night hit drama “NCIS,” “Late Show with David Letterman,” “The Late Late Show with Craig Ferguson” and “The Early Show.”

Ratings for the network’s late night programs, in particular, have shown notable increases. CBS’s “Late Show with David Letterman” has added 200,000 (+5%) new viewers while “The Late Late Show with Craig Ferguson” is up 100,000 viewers (+7%) since the YouTube postings started. Although the success of these shows on YouTube is not the sole cause of the rise in television ratings, both companies believe that YouTube has brought a significant new audience of viewers to each broadcast.

“Above all the other good news, what’s most exciting here is the extent to which CBS is learning about its audience as never before,” said Quincy Smith, President, CBS Interactive. “YouTube users are clearly being entertained by the CBS programming they’re watching as evidenced by the sheer number of video views. Professional content seeds YouTube and allows an open dialogue between established media players and a new set of viewers. We believe this inflection point is the precursor to many exciting developments as we continue to build bridges rather than construct walls.”
