According to the analysis, which MediaRadar exclusively provided to Adweek, the major TV ad spenders are the usual brand suspects, including Procter & Gamble, Berkshire Hathaway, Amazon, AT&T, T-Mobile and PepsiCo, along with auto brands General Motors, Ford, Hyundai and Toyota.

Overall, though, the retail industry spent more on television ads in 2019 than any other, accounting for nearly 15% of all national TV ads.

“Increased spend from ecommerce sites such as Amazon, Wayfair and even smaller sites like Etsy moved the needle enough to make retail 2019’s biggest TV ad-buying industry,” said Todd Krizelman, CEO and co-founder of MediaRadar, in a statement about the findings.

More than 2,000 brands were new to television advertising, including DTC brands like courier Postmates, fitness company Mirror and financial services firm Robinhood. Brands that were newcomers to television advertising spent more than $1 billion combined on TV ads this year.

TV ads got shorter in 2019, clocking in at an average 24 seconds in length compared to last year’s 26 seconds. Fifteen-second ads were more popular in 2019 than they were a year ago, accounting for 57% of all TV ads in 2019. Thirty-second ads, meanwhile, accounted for a little more than a third of all TV ads. The percentage of 60-second ads dropped on TV from 7% to 5%, MediaRadar found.

Those results are a continuation of previous reports, including from MediaRadar, showing that preferred TV ad lengths among advertisers is shortening. “We have once again found the 15-second ad length to be the crowd favorite,” Krizelman said.

TV advertising spend has remained a crucial part of the equation for established and upstart companies alike. The top 125 DTC brands spent $3.8 billion on TV advertising in 2018, according to a June report from the Video Advertising Bureau. Connected TV spend, especially, is on the rise: According to a November eMarketer report, connected TV advertising spend will reach nearly $7 billion by the end of this year.
