Marvel had definitely something big in mind when it came up with the Netflix series "Daredevil" last year, and after the announcement of other TV and web series like "Luke Cage" and "Jessica Jones", it was apparent that the studio was all set to create a live-action universe on TV just like its big-screen counterparts of Marvel Cinematic Universe (MCU).
"Daredevil" and "Jessica Jones" have already been received well by fans, with Season 2 of both shows on their way. With "Luke Cage", which is scheduled to air this year, and "Iron Fist", Marvel is all set to group all four for the spin-off series "The Defenders".
With ABC shows "Agents of SHIELD" and "Agent Carter", it seems the future of Marvel's television universe is bright. However, the question remains: How it will alter MCU, if at all?
There have been several instances, both in "SHIELDS" and "Daredevil", that link to the events of Avengers" one way or another. For example, Lady Sif from "Thor" has made an appearance on "SHIELD", while Wilson Fisk has mentioned the aftermath of the events that led to the story of "Avengers".
"Jessica Jones" Season 1 had a crossover with "Daredevil" as Claire Temple aka Night Nurse (Rosario Dawson) appeared on both shows.
Since the character of Luke Cage was first introduced in "Jessica Jones", there has been a significant possibility that it the opposition will happen, and other characters like "Iron Fist" and "Nova" will also make an appearance in "Luke Cage".
"Daredevil" Season 2 has confirmed the debut of Punisher and Elektra — two other prominent Marvel Comics characters.
Though there has not been any confirmation on whether the show will include elements from MCU's upcoming "Captain America: Civil War", given the history of Marvel's shows, it is definitely a possibility.
With so many interconnecting stories going within Marvel's cinematic and television universe, it is very likely the plot of the movies might get affected or modified by the shows' stories. However, as much as fans want it to happen, there has been no such confirmation or hint from the show-runners yet.
