James Wright bought a 4K TV and suddenly Comcast's terabyte cap hit him. I've written before that Comcast's terabyte cap was reasonable. Bandwidth is cheap but it isn't free. That is no longer true. The bandwidth needed has gone up ~30% per year. The cap hasn't risen despite the cost to deliver each bit has gone down dramatically. The cap is now hindering cordcutting. 

OpenVault found the average bandwidth use in 2019 in the US was 271 gigabytes, up 25%. Five years ago, very few drew a terabyte per month. Now, the number is meaningful and rising, particularly among those who don't take cable TV. Internet-only households consumed 85% more bandwidth, 390 GB per month. 

Many 4K TVs now cost US$300-700, including a remarkable new one from Huawei. A typical American home watching 4 hours of TV a day at 4K is close to the terabit. Add a kid or two, and overages will be hard to prevent.  

The European average in 2019 is 170 GB, up 28%. Unless Comcast rapidly raises the cap, users are pressured into taking Comcast's TV.
