Despite the increasing adoption of streaming media services and the convenience they offer, consumers still largely prefer good old-fashioned physical disks when they want to watch a movie, according to a new report from The NPD Group.

The report, which is based on a survey of approximately 21,752 U.S. consumers, revealed that the majority of feature-length movies are still rented on physical discs. Sixty-two percent of all movie rental orders during the first half of the year were for physical DVDs or Blu-ray discs that came from kiosks, video stores, and Netflix movies by mail. The other 38 percent were for digital copies of movies from subscription streaming, pay TV Video on Demand (VOD), and Internet VOD services.

But while physical discs still rule the movie rental scene, digital movies are catching up. Year-over-year disc rentals declined by 17 percent, while digital movie rentals increased by 5 percent, according to the report. The increase in digital movie rental orders is largely attributable to Netflix Watch Instantly.

"Kiosk and subscription Internet streaming are generating strong user satisfaction ratings, including future rental intent, price, and value, which is reflected in market-share gains," Russ Crupnick, senior vice president of industry analysis for The NPD Group, said in a statement. "Netflix is frequently the most popular video application on connected devices, so an increase in households with Web-connected Blu-ray Disc players, tablets, and smart TVs will lead to still more video streaming activity."
