This article could have digital video and home video, and cable tv at one time replacing the streaming aspect and get a similar result.
From your link, this is particularly troubling and bad research presentation :
a) Theaters vs. Streaming: The rise of streaming services has led to a decline in theater attendance. According to the Motion Picture Association, global theater attendance dropped by 4% in 2021, partly due to the availability of films on streaming platforms. The convenience and affordability of streaming services have attracted viewers to opt for at-home entertainment.
Theaters were still closed all over the world in a large scale global event.
Streaming services have been around longer than 2021. There have been a few newcomers since 2019.
And the correlation of 2020 being the year before that and 2021 recovering pandemic seems far more of a reason for the 4 percent than the streaming service impact would be. It seems rather silly that this even has to be said. Not only was there sitll a pandemic active in waves globally, as the numbers reference global, where the impact was often greater than the US, but less productions were occuring for theatrical release. For Studios, it was their ONLY option to make money since theaters were not allowed to open in many parts of the world.
As we have discussed, theatrical attendance has risen since then, with more streaming media than ever, not shrunk.
It has been easier to watch entertainment from home for a long time. I don't think there is any evidence showing this is a likely trajectory.
I appreciate your change of heart in wanting to discuss it though.
