New research shows that a quarter of all digital music consumed online in the UK is acquired illegally, Metro reports.
The study also found that online copyright infringement accounted for a third of film streaming, a fifth of TV shows, video games and an eighth of ebooks accessed during a three-month period analysed by Ofcom.
The results revealed that 16% of users aged 12 and above accessed content illegally at least once between May and July this year.
Music industry experts have previously claimed that illegal downloads and streaming cost artists £200 million a year, insisting the need to educate people on how to legally access content.
Liz Bales, director general of the Industry Trust for IP awareness, said: "It's also crucial to help them appreciate the value of film, TV and video and the role copyright plays in safeguarding the future of the entertainment they love."
A recent report by Virgin Media showed that two in five people admit to illegal downloading.
