Earlier today, Netflix released a new official teaser for its upcoming "Defenders" series, which unites street-level Marvel Cinematic Universe characters like Daredevil, Jessica Jones, Luke Cage and Iron Fist. The 16-second video shows the four protagonists riding in an elevator and reveals the series release date -- but that's not all. In the top left-hand corner of the footage of the clip, there's an Easter egg that leads to even more content.

As seen in the screen cap below, the video includes a specific set of numbers: 23.253.120.81. When typed into Google, those numbers lead to http://nybulletin.com/, the "official" New York Bulletin website.

The New York Bulletin website includes a series of front pages as well as a video with Joy and Ward Meachum, in which the two "Iron Fist" antagonists discuss coming into Rand Enterprises after the death of their father Harold. Joy also addresses the idea of the "Rand Enterprises curse," so called because the co-founders both died tragically young. Joy quickly shoots down the idea, preferring to deal "in reality," though fans of Marvel's Netflix shows will know that the idea of such a curse is nothing to scoff at.

Additionally, the New York Bulletin website includes a series of front pages that link directly back to this corner of the MCU. The first refers to the "earthshaking groundbreaking" at Midland Circle. If that looks familiar, look no further than the photo above. As it turns out, Daredevil, Jessica Jones, Luke Cage and Iron Fist are all in an elevator at Midland Circle Financial. They're going straight down, which may mean that they're headed to confront whatever the Hand was planning for in "Daredevil" Season 2 and "Iron Fist." What's more, the page touts a nameless "Crackpot Scientist" seeking a "lost city"; seeing as he takes such a prominent place on the paper, he may have something to do with the events of "Defenders."

The other pages all refer to events we've seen over the course of the shows, like Danny Rand's return to Rand Enterprises, Luke Cage's arrest, the mysterious disappearance of Daredevil and the Walker family's adoption of Jessica Jones. Colleen Wing and Claire Temple also get shout outs; Colleen has her own interactive page for her dojo, and Claire is honored as a "Hero of New York."

Executive produced by Douglas Petrie, Marco Ramirez, Drew Goddard and Jeph Loeb, “Marvel’s Defenders” arrives on Netflix in 2017 and stars Charlie Cox, Krysten Ritter, Mike Colter, Finn Jones, Simone Missick, Elodie Yung, Deborah Ann Woll, Elden Henson, Carrie-Anne Moss, Eka Darville, Rosario Dawson, Rachael Taylor, Scott Glenn, Jessica Henwick and Sigourney Weaver.
