The cable lobby group NCTA claims the industry has been investing record amounts in network upgrades, which will dry up if they are forced to endure Net Neutrality. Techdirt points out that Big Cable's numbers are cumulative, and re-runs them year on year. Turns out investment has been flat since about 2000.
From there, the story of cable continually increasing investment looks... very different. There was that big initial build-out of broadband in the late 90s/early 2000s, but then expenditures dropped, and other than minor ups and downs it's been pretty flat. In fact, since 2007, the trend is pretty clearly downward on investment. Yes, there's a tiny bump in the last two years, but that's at best flat spending, not any real increase.
Now, it's possible to claim -- as some cable industry supporters have been -- that because of greater efficiency and better technology, spending the same amount is fine because they get more value out of fewer dollars. But, if that's the case, then that's the argument the cable industry should be making, rather than the wholly misleading argument that investment in infrastructure has continued to rise over the last decade. It's quite clear from the chart that this is simply not true
