Following recent updates concerning Marvel Television's Netflix shows, Agents of SHIELD could be next to be officially integrated into the MCU. Marvel Television's Agents of SHIELD premiered in 2013 in conjunction with the theatrical releases of the MCU, as Agents of SHIELD's early seasons were informed by the action of MCU projects such as The Avengers, Thor: The Dark World, Captain America: The Winter Soldier and Avengers: Age of Ultron. Despite being initially tied to the MCU, later seasons explored wildly different stories, fueling a decade-long discussion regarding whether Marvel Television's Agents of SHIELD is actually canon to the MCU.
