LOS ANGELES (AP) – Netflix is adding to the group of movies that its subscribers can watch online or over Internet-connected devices at the same time as they would have appeared on premium pay-TV channels such as HBO or Showtime.

The deal announced Tuesday with film financier Relativity Media adds to a batch of newer movies from Disney and Sony that can be watched online through Netflix' 2-year-old deal with Starz Entertainment on a service called Starz Play.

With new movies from Relativity available early next year, about one-fifth of the rental movie chain's 100,000 movie and TV show titles can now be streamed online.

The company is gradually transforming itself from a mail-order DVD service to one that makes available content online over game consoles, Blu-ray players, mobile devices and TVs.
