A fifth of music downloaders in the US have also downloaded full-length motion pictures, leading research shows.

Ipsos-Insight’s quarterly digital-music study Tempo reveal that 21 per cent of American downloaders aged 12 and over have downloaded a full-length motion picture.

The research reveals 37 per cent of 18- to 24-year-olds have downloaded a full-length motion picture from the Internet. Men are more than twice as likely than women to acquire a digital motion picture online.

Ipsos-Insight’s technology and communications practice senior analyst Matt Kleinschmit said: "The data is evidence that American downloading behaviours are expanding beyond music and moving towards broader digital entertainment acquisition and consumption behaviours.

"While the music industry continues to define and integrate the role of digital music in the existing music marketplace, the motion-picture industry is presented with a unique foresight into next-generation consumer entertainment.

"Multimedia-enabled portable devices, digitally formatted television content, and downloadable back catalogue videos are just a few of the categories that may be mined in anticipation of near-future consumer demand.”

The research also revealed that nearly two-fifths (38 per cent) of American downloaders have downloaded a music video from the Internet, and 15 per had done so within the month before the survey.

Downloading of music videos is popular among 18- 24-year-olds and 25-34-year-olds (49 per cent and 43 per cent, respectively). Nearly half (45 per cent) of all male American downloaders have taken part in this digital downloading activity.
