While Walmart sits on the streaming sidelines, the competition is moving on. Netflix’s subscription-based approach -- featuring cutting-edge, exclusive content such as “House of Cards” and “Stranger Things” -- has been on a global-growth tear. Amazon’s spending billions on its own programming to catch up while offering hit shows from HBO and Showtime. And Disney is planning its own streaming service, which will debut in 2019.

All told, there are more than 200 over-the-top video services, so called because they bypass cable providers and stream content directly to a TV, laptop, phone or game console. That’s up from 68 five years ago, according to market researcher Parks Associates.
