ABC won’t start airing Joss Whedon’s “Agents of S.H.I.E.L.D.” until the fall, but the network isn’t holding out on getting fanboys — or the audience that made “The Avengers” a $1.5 billion hit — excited for the Marvel show.

Just hours after it officially picked up the show, ABC began promoting a preview for the series that features Agent Phil Coulson, a S.H.I.E.L.D. agent played by Clark Gregg, who was seen in Marvel’s “Iron Man,” “Thor” and “Avengers” films.

Full promo aired during the season finale of “Once Upon a Time,” on May 12, a move clearly meant to help boost the ratings for the ABC fantasy tale.



ABC also introduced a six-second Vine, featuring footage from the show.

“We Are the Rising Tide” also launched, featuring short blog posts on random superhero or villain sightings. Network will use the site to introduce new updates of “Agents of S.H.I.E.L.D” moving forward.

Naturally, the official Twitter feed and Facebook site were already up and running to get people excited about the unveiling of the show’s first visuals.

ABC posted the official full-length trailer to the show on May 14.
