So it seems everyone was really caught off guard by this release

Now I just watched it literally 3 minutes ago, but here's my thoughts:

First off, when does this take place? There is no date in the description, there is no unlisted video. It might be that Kane forgor to put them in yet but here's what I think. The broadcast played has yet to be identified, but seeming as it talks about American and Soviet debt, and mentions 25 years, it is safe to assume it takes place around 25 years after WW2. Additionally, the document shown in the end signed by Ivan Beck is dated in 1972. So, this likely places the video in the early 1970's. What is interesting, is that the end of I Remember shows old technology. So I think that we can infer from this that Ivan Beck has been trying to do backrooms stuff for many years. If the 1970's attempts were succesful or not isn't known yet. There is of course the possibility of the radio broadcast being time travelled forward, but I doubt this is the case (it is still possible though)

The event caused in Overflow seem to cause world tearing in the clouds, this is the same effect as in I Remember. The green light and sound from FF2 is also heavily featured, though at some points is yellow for some reason. Does this mean that 1970's experiment caused the backrooms to do trolling in the real world? The world seems fine enough well into the 2000's, so I doubt this had any lasting impact. Or perhaps this is the very end of the timeline? It would have to be much later than anything we have already seen though. Can't have the world end in 1990 when we have FF1 showing stable 1996, and home_27647 showing footage of 2000's. And the radio heard in Pitfalls also comes from around the same time period. The world tearing hasn't shown to cause anything actually changing, it's just that perspective changes. (Talking about I Remember effect). The real question is what happened to the green light? What does it actually do?

My current theory (after thinking for 5 minutes, so this probably isn't true) is that Ivan Beck has tried to do Beckin' time into the backrooms since at least the 1970's, and at some point an experiment went wrong that caused unknown damage. But years later in the 1980's they managed to make it more stable (but still does some trolling in the real world).
