Comcast says its customers' monthly median data use rose to 200GB in Q1 2018, up 34% YoY, driven by streaming video, especially in 4K

Context & Ripple Effects
By 2015 Comcast had already crossed the line where internet subscribers outnumbered cable TV customers, so its business was migrating from selling video bundles to carrying everyone else's. The 200GB median reported here is the consumption side of that flip — and it sits directly against the pricing structure Comcast built earlier: the [[a:868723|2016 decision to raise its data cap from 300GB to 1TB while charging an extra $50/month for unlimited]].
The trajectory only steepens afterward. Two years later OpenVault found the share of subscribers using at least 1TB monthly had more than doubled year over year (8.8% vs 4.2%), and pandemic-era measurement showed peak traffic up another third on top of that (32% over pre-pandemic levels) — meaning this 34% YoY jump was an early reading of a curve, not a one-off.
First-order effects
- Heavy-streaming households — especially 4K viewers, whose sessions consume multiples of SD streams — move measurably closer to the 1TB cap Comcast set in 2016, making the $50 unlimited add-on a live purchase decision rather than an edge-case option.
- Comcast gets a usage-growth datapoint it can use internally to justify capacity planning and externally to defend or recalibrate cap tiers.
Second-order effects
- As medians climb toward thresholds that were once ceilings, the effective price of unmetered streaming rises for Comcast's base unless caps are raised again — putting pressure on the 300GB-to-1TB tiering to keep moving upward just to stay out of the typical bill.
- Rival ISPs competing for the same streaming households face matching demand curves; whoever offers flat unlimited pricing gains a marketing wedge precisely against Comcast's metered structure.
Third-order effects
- If usage compounds faster than cap tiers adjust, metered broadband hardens into a second revenue engine layered on connectivity — with the cap level itself becoming the key regulated-and-negotiated number between ISPs and their customers, not just a technical limit.
- The pattern points to video shifting fully onto ISP networks: the company that lost video-subscription primacy when internet customers overtook cable ones now monetizes the replacement activity through data pricing.
The trend: US household broadband consumption is compounding on the strength of streaming video, steadily converting Comcast's fixed data caps into an escalating pricing lever on the very activity that replaced its cable business.
