OpenVault study: 8.8% of US broadband subscribers used at least 1TB/month in Q3, up from 4.2% in Q3'19, and about 1% used at least 2TB/month, up from 0.36% YoY

Context & Ripple Effects
OpenVault's numbers put a marker on how far household consumption has traveled since Comcast reported a 200GB median in early 2018, when 4K streaming was already flagged as the driver. The doubling of the 1TB-plus cohort in a single year lands alongside supply-side growth: Ookla measured mean download speeds up 35.8% the prior year, so networks could actually deliver what heavier users demanded.
First-order effects
- ISPs face a fast-growing tier of subscribers whose usage sits at or past typical 1TB cap thresholds, forcing choices between overage billing and unlimited-tier upsell for exactly the customers Comcast already identified as streaming-driven.
Second-order effects
- Wireless networks absorb part of the same demand curve — CTIA later logged the largest single-year jump in US wireless data use — pushing both fixed and mobile operators toward capacity buildouts and usage-tiered pricing rather than flat all-you-can-eat plans.
Third-order effects
- If heavy-user share keeps compounding at anything like this pace, the industry's economics tilt toward metered or tiered data pricing as the default, with unlimited plans reserved as a premium product rather than the norm.
The trend: US household connectivity is normalizing terabyte-scale monthly consumption, moving broadband from a speed-sold product toward one priced and engineered around usage.
