Netflix (NASDAQ:NFLX) is following HBO's business model of creating original content to stay relevant in the media business. But the company doesn't have downstream revenue channels like cable networks or theme parks available to Disney (NYSE:DIS), Time Warner (NYSE:TWX.DL), or Comcast's (NASDAQ:CMCSA) NBCUniversal. Fool contributor Travis Hoium thinks that will limit Netflix's profit potential and keep it behind old media long-term.
