Dive Brief:

• EMarketer's newly-released report outlines estimates for digital ad spending in the U.S. for the coming year, and leading the digital ad growth pack are retailers.
• The eMarketer report predicts retailers will comprise 22% of the expected $58.61 billion in digital ad dollars spent this year in America.
• Retailers are also predicted to spend nearly twice as much as any other industry -- representing 23.2% of the $28.72 billion advertisers will spend on mobile in 2015. 

Dive Insight: 

Retailers perhaps have the most to gain from reaching users directly through digital means, especially on mobile. E-commerce is exploding -- particulary for packaged goods which are expected to hit $3 trillion in sales in the next five years -- and the growth explosion will benefit marketers as it creates stronger competition among e-commerce brands. The need to stand out among the crowd likely means retailers' investment in digital advertising will only increase.
