For the past decade or so, critics and fans have put forth the theory that we are living in a new Golden Age of Television thanks to acclaimed shows like "The Sopranos," "The Wire," "Breaking Bad" and "Mad Men." But if that's the case, then it looks like we just got upgraded to the Diamond Age, because ABC has officially picked up the coolest TV show ever conceived, "Marvel's Agents of S.H.I.E.L.D."

And thanks to YouTube, we've got the first promo spot right here.

Avengers, assemble!

Spinning directly out of the events of last summer's super blockbuster "The Avengers," "Marvel's Agents of S.H.I.E.L.D." features Marvel Studios mainstay Clark Gregg as S.H.I.E.L.D. agent Phil Coulson. Faced with more and more new superpowered menaces — and heroes — Coulson and his team of highly trained secret agents form the last line of defense between us and the world of supermen.

Of course, fans might be curious to know just how Coulson is around to lead this team, considering he apparently died at the hands of Loki in "The Avengers." That information, unfortunately, is not really hinted at in the trailer. But considering the series pilot is directed by "Avengers" mastermind Joss Whedon, chances are "Marvel's Agents of S.H.I.E.L.D." features plenty of cool Easter eggs designed to answer that question and many, many others as it ties together all the crazy strands of Marvel's big screen universe.

Now this is what we call real destination television.
