Sziget launched the YouTube feeds for the first time this year, giving would-be festival-goers a chance to see 55 concerts on three stages.
The feeds were watched the most in Hungary, Belgium, the Czech Republic and the UK.
About 60,000 comments were posted on Sziget?s official YouTube channel over five days.
Pál Bíró, who is in charge of YouTube at Google Hungary, said the Sziget Festival was one of the most popular music events on YouTube in Europe.
Festival organiser Károly Gerendai said the viewer numbers were well over expectations.
Sziget highlights can be seen on the festival?s YouTube channel - youtube.com/szigetofficial ? for another three months.
