CBS’s “Supergirl” and Fox’s “Scream Queens” are leaps and bounds ahead of other freshman fall TV broadcast shows in terms of fan anticipation and engagement on major social-media platforms, according to research from ListenFirst Media.

“Supergirl,” set to premiere on the Eye on Monday, Oct. 26, has accumulated 15.5 million engagements on Facebook, Google+, Instagram, Tumblr, Wikipedia and YouTube in the 90 days after CBS announced the superheroine show at the upfronts in mid-May, according to ListenFirst’s Digital Audience Ratings system for TV. Campy horror-comedy “Scream Queens,” set to bow Sept. 22 on Fox, has garnered a DAR-TV rating of 14.3 million over that time frame, followed by CW’s “Legends of Tomorrow” at 8.7 million, NBC’s “Heroes Reborn” at 7.4 million and ABC’s “Quantico” at 2.5 million.

Of course, solid social-buzz metrics are no guarantee that a show will be a hit — or that it will even remain on the air. But TV programmers are eager to build social followings for new shows, given that fan excitement can serve as low-cost marketing for their latest fare.

“Supergirl” became a force to be reckoned with when CBS released a first-look trailer following the Upfront presentation. Since posting, the video has garnered 14.3 million engagements across Facebook and YouTube. The show may also have received a boost after the pilot episode leaked to piracy sites one week later.

“Scream Queens” had a strong presence across every platform ListenFirst analyzed (with the exception of Google+ and organic search volume), and specifically established itself as the No. 1 program on Instagram because of high engagement from posts by show’s cast including Ariana Grande.

It’s worth noting the top three frosh TV broadcast shows as ranked by ListenFirst each had a presence at this year’s Comic-Con in San Diego.

“While upfronts were certainly the initial boost for all these programs, Comic-Con really provided a tremendous opportunity to regain momentum and tide fans over until fall premieres,” said Jason Klein, co-CEO of ListenFirst.

Rounding out the top 10 most-buzzed-about new broadcast shows, per ListenFirst’s tracking of activity 90 days post-Upfronts, are: ABC’s “The Muppets” (2.5 million), Fox’s “Minority Report” (2.3 million), Fox’s “Grandfathered” (2.0 million), Fox’s “The Grinder” (1.5 million) and CBS’ “Limitless” (1.4 million).

ListenFirst doesn’t include Twitter activity in the DAR-TV report; Nielsen has an exclusive partnership with Twitter to track social ratings for TV shows. On Twitter, “Scream Queens” has the most number of followers among freshman broadcast TV shows with 114,000, followed by “Heroes Reborn” at 69,000-plus, “Supergirl” at 32,500, @TheMuppetsABC at 17,000, @QuanticoTV at almost 10,000 and CBS’s “Angel From Hell” at 5,500.

The ListenFirst DAR-TV ratings are a raw aggregate of daily engagements based on owned, earned and organic consumer behavior on Facebook, Google+, Instagram, Tumblr, Wikipedia and YouTube. These engagements encompass metrics pertaining to audience growth, page/profile views, page-level and post-level interactions, hashtag volume and Wikipedia page views for all television program pages (which provides a proxy for organic search volume).
