US cable Internet customers are using an average of 268.7GB per month, and 4.1 percent of households use at least 1TB, according to
new research by the vendor OpenVault.
Households that use at least 1TB a month are at risk of paying overage fees because of the 1TB data caps imposed by Comcast and other ISPs. Terabyte users nearly doubled year over year, as just 2.1 percent of households hit the 1TB mark last year, according to OpenVault.
Median usage rises 40%, year over year
But Comcast isn't the only major home Internet provider imposing caps and overage fees. AT&T, the
third-largest home Internet provider,
imposes capsranging from 150GB to 1TB a month and
chargesoverage fees of $10 for each additional 50GB. AT&T customers can get unlimited data by purchasing the gigabit speed tier, by bundling AT&T Internet with TV service, or by paying $30 extra per month.
