As predicted by Edholm’s Law, internet access speeds continue to climb. AT&T, for example, just activated symmetrical 2-Gbps and symmetrical 5-Gbps service for 5.2 million locations across 70 U.S. markets, with plans to deploy across the whole footprint in 2022 and later years.
Edholm’s Law states that internet access bandwidth at the top end increases at about the same rate as Moore’s Law suggests computing power will increase.
Nielsen's Law, like Edholm’s Law, suggests a headline speed of 10 Gbps will be commercially available by about 2025, so the commercial offering of 2-Gbps and 5-Gbps is right on the path to 10 Gbps.
Headline speeds in the 100-Gbps range should be commercial sometime around 2030.
How fast will the headline speed be in most countries by 2050? Terabits per second is the logical conclusion. Though the average or typical consumer does not buy the “fastest possible” tier of service, the steady growth of headline tier speed since the time of dial-up access is quite linear.
And the growth trend--50 percent per year speed increases--known as Nielsen’s Law--has operated since the days of dial-up internet access. Even if the “typical” consumer buys speeds an order of magnitude less than the headline speed, that still suggests the typical consumer--at a time when the fastest-possible speed is 100 Gbps to 1,000 Gbps--still will be buying service operating at speeds not less than 1 Gbps to 10 Gbps.
Though typical internet access speeds in Europe and other regions at the moment are not yet routinely in the 300-Mbps range, gigabit per second speeds eventually will be the norm, globally, as crazy as that might seem, by perhaps 2050.
The reason is simply that the historical growth of retail internet bandwidth suggests that will happen. Over any decade period, internet speeds have grown 57 times. Since 2050 is three decades off, headline speeds of tens to hundreds of terabits per second are easy to predict.

Of course, the typical consumer customer does not typically buy the top-available speed at any given point of time.
AT&T Fiber 2 GIG costs $110 per month plus taxes. AT&T Business Fiber 2 GIG costs $225 per month plus taxes. The “typical” consumer household probably now pays about $50 a month for internet access.
AT&T Fiber 5 GIG: $180 per month plus taxes. AT&T Business Fiber 5 GIG costs $395 per month plus taxes.
The point is not that so many consumer households will buy the top offers. The point is that--with higher “fastest” speed tiers, the typical buyer also tends to move up. As more customers buy the 2-Gbps or 5-Gbps services, a change in the adoption rate will happen when we hit about 10-percent adoption of either service.
Adoption of 1-Gbps service now has passed the 10-percent point, so we should see accelerated adoption of gigabit services. Where half of U.S. consumers now buy services in the 100 Mbps to 200 Mbps range, we should see a shift of those buyers to higher-speed services over the next few years, as the top end also continues to move.
Once 2-Gbps adoption hits about 10 percent of households, half of the rest of the market will start to move to speeds more in the range of 400 Mbps. Once 5-Gbps adoption hits about 10 percent, half the market will start a move towards gigabit service, history suggests.
