I now sign up for 1-2 months a year to catch up on shows I like and just rotate which streaming services I have. Yes, this is anecdotal.
It's hard to find data on how common rotating streaming services is. I would guess not common. I found this from 2021 showing the number of streaming services the average US household has [1]. It's worth noting that this was based on lockdown-era data.
The number if still quite high. I still have 3-4 mainly because my ISP gives me 1 and Amazon Prime bundles it. Were it not for those, I'd probably stick with 2. This is imperfect data because is it the same 4 or are some or all of these rotated? We just don't know.
Most of the data around this is how streaming is cannibalizing satellite and cable. But at this rate Netflix will cost $30+ in 10-15 years. Will it still have growing revenue and the same subscriber numbers? There is price elasticity here.
