The Consumer Technology Association (CTA) said the Trump Administration's proposed 25% tariff on TVs from China, such as the TCL and Hisense brands, would cost consumers $711 million in the next year alone.

That is according to a just-released study commissioned by CTA and the National Retail Federation.

TVs are just one of more than a thousand products facing tariffs, the groups said, all potentially hitting consumers' pocketbooks.

"These proposed [TV] tariffs are bad for the economy, businesses and American consumers," said CTA CEO Gary Shapiro, who suggested that the threat of such tariffs had already had the desired effect of getting China to open the door wider for U.S. products.

"Now that China has expressed some willingness to open its market and strengthen protection of intellectual property, the Trump administration should immediately initiate negotiations," said Shapiro.

CTA said it agrees China's unfair trade practices need to be addressed, but not by punitive tariffs where those punished are consumers.

"A TV made in China that costs $250 today would cost $308 after the tariffs are applied," the CTA said, citing the study, "and one that costs $500 today would cost $615 after the tariffs are applied."

Despite the growing number of ways people can watch video content, 92% of all viewing by U.S. adults is done on a TV screen, according to Nielsen.

Nielsen’s fourth-quarter "Comparable Metrics Report" found that adults spent 509 billion minutes viewing on TVs in the quarter and another 63.6 billion minutes viewing on TV-connected devices. Viewing video on PCs accounted for 31.7 billion minutes, smartphone video for 10.9 billion minutes and tablets for 4.4 billion minutes, for a combined share of viewing of 7.6%.

TV has a weekly reach of 89% of all adults, but only 79% of millennials (adults 18-34). TV-connected devices reach 44% of all adults and 54% of those 18-34.

Those young adults spent more time on their phones — 19 hours, 39 minutes per week — than watching the tube, at 19:18, according to Nielsen. Among all adults, 34 hours, 32 minutes per week were spent watching TV, with another 4:18 on TV-connected devices. They spent 17:48 per week on their phones.

Nielsen said its "Comparable Metrics Report" is an in-depth study of users and usage — averaged across the U.S. population — designed to provide an “apples to apples” view of consumption across TV, radio, TV-connected devices, PCs, smartphones and tablets.

“The fact of the matter is that viewers use the TV screen for the bulk of their viewing and spend more time doing so than all the other platforms combined,” said Tom Ziangas, SVP Research at AMC Networks. “Sure, viewers have more options today, but when looking at platforms in a comparative fashion, it’s clear that consumers choose the television as the primary vehicle for content,” he added.

The average number of TVs in homes is on the decline, according to the Department of Energy's U.S. Energy Information Administration's most recent figures, while younger households have higher concentrations of broadband content-access devices.

According to its latest Residential Energy Consumption Survey, there are an average of 2.3 TVs per home in 2015, down from 2.6 in 2009.

In addition, a larger share of homes reported not using a TV set at all. In fact, the percentage doubled from 1.3% in 2009 to 2.6% in 2015.

The survey found that "younger households tend to have a lower concentration of televisions per person and a higher concentration of portable devices such as laptops and smart phones. Older households are more likely to have higher concentrations of desktop computers."

According to DOE, TVs, cable boxes, DVRs and video game consoles account for 6% of all residential electricity consumption in the U.S. (Editor's note: The story initially said it was 6% of all electricity consumption. We regret the error.)

The survey looked at more than 200 energy-related items from more than 5,600 households.
