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.
