Netflix (NASDAQ: NFLX) expects advertising to be a big part of its business. On its fourth-quarter earnings call, outgoing co-CEO Reed Hastings asked CFO Spence Neumann how many years it'll take the company to surpass Hulu's advertising business. The Hulu streaming service, controlled by Walt Disney (NYSE: DIS), had a 15-year head start on Netflix in advertising, and it has grown to become a leading seller of connected TV advertising in the United States.
