The The Avengers.
With Daredevil a success, more Marvel/Netflix ventures arrived, with Samuel L. Jackson's Nick Fury) feeling incompatible with the MCU in later seasons.
Nevertheless, fans of the Marvel Netflix shows have often sought out connections to other, non-streaming, MCU properties to try and tie the likes of Daredevil to the same world inhabited by Spider-Man: Far From Home. But Kiernan has also appeared in Daredevil, The Punisher and The Defenders.
Although Pat is obviously playing himself in these roles, the fact that both the MCU movies and Marvel's Netflix shows have the same news outlet starring the same lead news anchor does provide one of the few connections between the two entities. All of these characters are technically supposed to exist within the same continuity, of course, but this is rarely exhibited on Netflix.
Unfortunately, this theory is somewhat undone by Pat Kiernan's selection of other appearances reporting the end of the world or similar events in a selection of other movies or TV shows. Specifically under the Marvel umbrella, Pat can be spotted in Ghostbusters reboot, neither of which fit neatly alongside the MCU (although the Golden Tablet of Akhmenrah would for a lot).
Perhaps if Pat Kiernan's fictional appearances were limited strictly to Marvel fare, his presence could be used to tie certain properties into one singular universe, but the anchor has earned a reputation as being Hollywood's go-to guy when a fictional disaster needs reporting on. While he alone may not be enough to bring together the MCU and Marvel's Netflix shows, Pat's work in the franchise does deserve recognition, with his scenes regularly adding real-world gravity to major story moments without taking any attention away from the superheroes themselves.
