American consumers are cancelling traditional pay-TV service at a much faster rate than previously expected, according to research firm eMarketer.

In 2017, a total of 22.2 million U.S. adults will have cut the cord on cable, satellite or telco TV service to date — up 33% from 16.7 million in 2016 — the researcher now predicts. That’s significantly higher than eMarketer’s prior estimate of 15.4 million cord-cutters as of the end of this year. Meanwhile, the number of “cord-nevers” (consumers who have never subscribed to pay TV) will rise 5.8% this year, to 34.4 million.

“Younger audiences continue to switch to either exclusively watching [over-the-top] video or watching them in combination with free-TV options,” said Chris Bendtsen, senior forecasting analyst at eMarketer. “Last year, even the Olympics and [the U.S.] presidential election could not prevent younger audiences from abandoning pay TV.”

Overall, 196.3 million U.S. adults will have traditional pay TV (cable, satellite or telco) this year, down 2.4% compared with 2016, eMarketer predicts. By 2021, that will drop to 181.7 million, a decline of nearly 10% from 2016. The number of pay-TV viewers 55 and older will continue to rise over the next four years, while for every other age cohort the subscriber numbers will decline.

By 2021, the number of cord-cutters will nearly equal the number of people who have never had pay TV — a total of 81 million U.S. adults. That means around 30% of American adults won’t have traditional pay TV at that point, per eMarketer’s revised forecast.

 

For the TV biz, there’s another worrisome trend: People are watching less traditional television. For the first time, in 2017 average TV viewing in the U.S. is expected to drop below 4 hours per day, eMarketer predicts.

Average time spent watching TV (excluding digital) among American adults will drop 3.1%, to 3 hours 58 minutes this year. Digital-video consumption, meanwhile, continues to climb. U.S. adults will consume 1 hour 17 minutes of digital video per day on average in 2017 (excluding time spent viewing video on social networks), up 9.3% year over year, according to eMarketer.

This year, TV advertising will increase just 0.5%, to $71.65 billion (versus the firm’s previous $72.72 billion forecast). As a result, the TV sector’s share of total U.S. media ad spending will drop to 34.9% (vs. 36.6% in 2016) and is expected to fall below 30% by 2021.
