Most US viewers stream video, either in lieu of or in addition to broadcast or cable according to a Multichannel News analysis of data from the National Telecommunications & Information Administration (NTIA).

Age matters: The majority (86%) of internet users 15-24 watched video online in 2017, compared to 40% of those over 65.
Meanwhile, three-quarters (73%) of US households had a cable or satellite subscription in 2017, and 67% of them also watched online video.
About 40% of the remaining households identified as cord-cutters (and 82% watched video online); and 60% had never had a traditional TV subscription (71% watched online video).
"These results suggest that while cost and personal preferences dominate decisions about purchasing cable or satellite television services, the availability of internet-based video services is also influential," said Carlson.
Cord-nevers tend to be younger and lower-income and less likely to be non-Hispanic white. Cable households are mainly over 50, and less likely to have children living at home.
