MAGNA GLOBAL estimates US programmatic display ad spending will reach $7.5 billion this year. Over the next several years, programmatic display ad spending growth rates will begin to level off—a sign of a market nearing maturity. Still, by 2017, the company predicts the amount of US digital display ad dollars transacted via programmatic channels will total nearly $17 billion.
