And 29 percent of TV-watching adults use them daily

The number of U.S. TV homes with at least one internet-connected TV device continues to swing upward, Leichtman Research Group (LRG) found in a new study.

Some 74% of those homes have at least one such device in a category that includes smart TVs, standalone streaming players, streaming adapters and sticks, and connected Blu-ray players, LRG said in the study, "Connected and 4K TVs XV," which based findings on a survey of 1,202 U.S. TV homes.

The 2018 results are up from 65% in LRG’s 2016 study, 44% in 2013, and a mere 24% in 2010.

LRG said 29% of adults in U.S. TV homes watch video on a TV via a connected device daily, up from 19% in 2016, 6% in 2013, and 1% in 2010.

Tying into a broader trend that has seen younger viewers gravitate to OTT-delivered video, that group currently over-indexes in the 18-34 age group (43%), compared to 33% who are 35-54, and 12% among those 55 years or older.

Per the study, about 29% of all TVs in U.S. homes are connected smart TVs, up from just 7% in 2014. Among homes with any connected TV device, 57% have three or more, with a mean of 3.8 devices per connected TV home.

Across all TV homes, the mean number of connected TV devices is 2.8, versus a mean of 1.7 pay TV set-top boxes per U.S. TV home

“Connected TVs, along with Netflix and other SVOD services, are among the biggest factors driving change in the video industry over the past few years,” Bruce Leichtman, president and principal analyst for LRG, said in a statement. “In a short period of time, connected devices have allowed an increasing number of consumers to easily watch SVOD and other video options on the same TV screen as traditional pay-TV and broadcast offerings."
