Declines in TV viewership have suppressed the medium's advertising dollars, according to research firm Magna Global, which released the data as part of report on the global ad business. Viewership fell sharply in Europe, compounding the trend in the U.S., China and Australia.
Traditional television has hemorrhaged viewers in recent years, as people trade cable and satellite packages for online services Netflix and YouTube.
Cord cutting has been especially pronounced in the U.S., the world's largest media market, and should continue to accelerate as media giants Walt Disney Co. and AT&T Inc. introduce their own streaming services.
Even with the retreat from TV, overall ad revenue climbed for the 10th year in a row. The industry was buoyed by digital sales, which rose 15%.
The TV business had previously eked out gains in advertising sales by charging higher prices. And it's still seen as a useful medium when marketers need to reach a large, live audience.
Technology companies excel at allowing advertisers to target individuals who have searched for a sweater on Google, liked a movie's page on Facebook or looked for detergent on Amazon.
Yet declines in viewership now outpace the rise in TV ad pricing. So-called linear TV viewership has been declining by 10% in the U.S., Australia and China for a few years, according to Vincent Letang, the author of the report.
European TV channels suffered drops of 7% to 8% among viewers age 18 to 49, worse than the 5% decline last year.
Worldwide Decline
"Almost everywhere now, we have linear viewing declining double digits, or high single digits," Letang said in an interview. He blamed the proliferation of streaming services, which took hold in Europe a few years later than in the U.S., as well as the slowing economies in the region.
U.S. TV ad sales will return to growth in 2020 thanks to the summer Olympics and the presidential election, but that is a temporary boost.
The TV industry isn't the only one suffering. Technology companies Google and Facebook Inc. have siphoned advertising dollars away from print publications and radio in recent years. Online companies garnered more than half of global advertising sales in 2019 for the first time, accounting for $306 billion of the $595 billion spent globally.
Radio advertising sales stabilized in 2019, while the out-of-home category — namely, billboards — was the only traditional media to actually grow. That's due in part to technology companies, which use billboards to tout their services. Facebook, Apple, Amazon, Netflix and Google all rank among the 20 largest out-of-home advertisers.
