Amazon Dominates This Industry Even More Than Online Retail
Amazon (NASDAQ: AMZN) will take a whopping 40% of online retail sales in the U.S. this year, but it's punching above its massive weight in another aspect of e-commerce. Advertising on Amazon's U.S. marketplace will generate over $18 billion this year, representing about 80% of marketers' spend on U.S. e-commerce sites, according to an estimate from eMarketer. Amazon's dominant position in e-commerce channel advertising is bad news for Walmart (NYSE: WMT), Target (NYSE: TGT), and other brick-and-mortar stores who rely on in-store promotions and advertising revenue as more shopping shifts online.
