Note the difference in values on the x-axis. NBC's trailers in general have been much more viewed on YouTube than those of the other networks. Is it an indicated of anything? Time well tell.
Like/Dislike Ratio
So it looks like YouTubers are really liking the shows on The CW, and not liking the ones on CBS. In fact, none of the CBS shows get a "A" grade in the like/dislike ratio. Also a huge difference in reception between ABC's two new comedies. Looks like the big winners are Designated Survivor, Son of Zorn, and Frequency.
