Which companies spend the most online ad time?

The U.S. is the largest online ad spender, but it’s also the least active, according to a new study from research firm Kantar Media/CMAG.

The research firm tracked online ad spending across multiple categories, and found that it’s mostly focused on targeted ads, while advertisers spend more than $1 billion a year on ads on the web.

The study shows that digital marketers spend roughly $300 million per year on online advertising.

This is the first time the study looks at spending in digital ads overall, and it found that digital advertisers spent $5.7 billion on online ads in 2017, up 1.1 percent from 2016.

That’s a jump of nearly 7 percent from a year ago.

The digital ad spend also grew at a faster rate than the overall ad spending, which grew by 0.3 percent.

But the report also notes that digital ads still accounted for less than one-third of the overall online ad market in 2017.

This means that digital ad spending will likely continue to lag behind overall ad spend.
