Even though it seems interest in digital content has increased over the past few months, research from the NPD Group reveals consumers in the United States are more interested in purchasing DVDs and Blu-ray Discs.

According to the "Entertainment Trends in America" report, 88 percent of consumers prefer DVDs and Blu-ray, with the average consumer spending $25 per month for video entertainment.   Not surprisingly, most of the money -- 63 percent total -- went towards DVD, with just 7 percent spent on the high-definition Blu-ray format.

Around 18 percent went towards DVD and Blu-ray Disc movie rentals through brick and mortar locations and movie rental kiosks.  Around 9% was dedicated towards video on-demand (VOD) services and just 3 percent was dedicated towards online streaming movies and TV episodes.

"While many in the home video industry worry that digital consumers might walk away from packaged media, that hasn't happened yet," NPD entertainment video industry analyst Russ Crupnick said.  "Discs are still and by far the dominant way Americans enjoy home video."

Many of the consumers who watch digital content also purchase DVDs and Blu-ray media, the research also found.  In addition to video sites such as Hulu, streaming content -- including Netflix -- is available through the Microsoft Xbox 360 game console and several standalone Blu-ray players.

As more viewers become aware of digital content and online streaming, it's more likely they'll begin to pay to watch streaming movies from home.  Last year, only five percent of people with internet at home watched streamed movies, but around 9% watched streaming content in 2009, NPD said in its report.

Sony and other Blu-ray supporters hope to see the format one day replace DVDs as the dominant physical format. As prices of players and movies continue to fall, more people are slowly embracing the format.
