Amazon, Samsung and American Express are among the biggest brands found to be placing adverts on pirate websites.
A list of major brands has been published by researchers at the USC Annenberg Innovation Lab – the team responsible for outing advertising networks servicing similar file-sharing websites at the beginning of the year.
The new list contains a number of companies with involvement in the music industry either as a direct player or a partner.
Online retailer Amazon can be found on the list, which is in alphabetical order rather than any kind of ranking, along with Samsung and Nokia, two mobile phone manufacturers who now have their own digital music offerings.
AT&T and American Express are two non-music brands that have significant partnerships in the music industry, with the former having close links with streaming service Spotify abroad.
The USC Annenberg Innovation Lab has also updated its list of the biggest ad network offenders with Google and AdClicks not appearing in the Top 10.
"Both Google’s various networks and Open X have significantly reduced the number of infringing sites they are placing ads on,” said the research team. “In contrast, Yahoo’s Right Media continues to be a major provider of ads to infringing sites."
Google was previously placed as the second most active ad network on the pirate sites, although the tech giant told Music Week that it had issues with the way the table was compiled.
