I would guess that the distribution today is at least somewhat bimodal based on whether someone pays for a live TV package whether cable, satellite, or streaming. Any of those probably cost at least $60/month (in no small part because of sports).
I expect that typical other streaming spend (Netflix, a la carte rentals, maybe a premium Print add-on or HBO, etc.) probably don't add up to more than $30-40 a month or so.
So $40/month. I'd add to that whatever the average blockbuster price was $5 * 4-weeks (quick googling didn't give me a great answer, but I found 2.18 GPB for 1995, so probably $3-5 with conversion and inflation).
That makes roughly $60/month for the average American at-home tv/movie spend in the 90s. I suspect that still is the rough tolerance.
