A quarter of US households are cord cutters

"Findings from market and consumer information firm GfK show that US TV households are embracing alternatives to cable and satellite reception. Levels of broadcast-only reception and Internet-only video subscriptions have both risen over the past year, with fully one-quarter (25 per cent) of all US TV households now going without cable and satellite reception.
The research, from GfK’s 2016 Ownership and Trend Report from The Home Technology Monitor, shows that 17 per cent of US TV households now rely on broadcast-only (a.k.a. ‘over-the-air’ or OTA) reception, up from 15 per cent in 2015. Another 6 per cent say they only use Internet services such as Netflix, Amazon Prime, Hulu, or YouTube and do not have traditional broadcast or pay-TV reception at all; this compares with 4 per cent a year ago.
TV households with a resident between 18 and 34 years old are much more likely to be opting for alternatives to cable and satellite; 22 per cent of these homes are using broadcast-only reception (versus 17 per cent of all US households), and 13 per cent are only watching an Internet service on their TV sets (versus 6 per cent of all TV homes). Overall, 38 per cent of 18-to-34 households rely on some kind of alternative TV reception or video source, versus 25 per cent of all homes."
