The title kind of buries important details about the distribution of these costs and their changes.
For example, Apple TV+ went from $4.99 per month to $14.99 per month, a +200% change, while YouTube Premium went from $11.99 to $15.99, a +33% change.
So services like Apple TV+ are skewing this increase a lot while services like YouTube Premium have remained relatively low. Similarly, Apple TV+ starting at $4.99 per month was clearly a very low price to start (which can probably be mostly attributed to the service's lack of content at that point). It's now at a "normal" price.
Just the same, saying something like something "costs $702/year more" without a point of reference is bad data presentation. The 2021 cost for all of these services was $1,150.92, for a +61% change. I'm not saying that's not substantial, but this kind of information is necessary for these figures to not just be rage bait.
And, of course, if you're simultaneously paying for Netflix, Disney+, Hulu, HBO Max, Apple TV+, Paramount+, Peacock, YouTube Premium, and Spotify every month, then you're either (a) really into consuming this kind of content and are a "premium subscriber" in the sense that these costs ought to be justified or (b) very bad with managing your time and finances. I suspect normal users subscribe to one or two of these at a time and are probably willing to switch around as prices change, content gets released/pulled, etc. A better analysis would try to do some investigation into this dynamic, since it will probably reveal that people are able to navigate dynamic service subscriptions well enough that they aren't actually experiencing a straight-up +61% increase in costs since 2021.
All of this is to say that this "analysis" barely even qualifies as a valid first-pass at understanding this kind of data. It's literally something that Claude probably churned out in 20 minutes. Everyone can be dissatisfied with the value they get from these streaming services, but this kind of post only helps to muddy the conversation.
