ISPs are spending less on their networks as they make more money off them

It turns out that, as a percentage of the money they pull in, Internet service providers (ISPs) have generally spent less on infrastructure over time -- from a high of 37 percent of revenue in some cases to a low of around 12 percent more recently. This affects how reliable your connections are, what kind of speeds you get and the amount you pay for service each month.

Some companies are building out fiber directly to the home. But not all; fiber is expensive. The question now is whether ISP spending will rise again to meet the new demand.
