The Creative Coalition Campaign has backed the government's decision to rush through new anti-filesharing laws before the dissolution of parliament.
Christine Payne, Chairperson of the organisation, which supports the interests of arts professionals, said acceptance of the digital economy bill marks "a groundbreaking day" for the UK's creative industries.
She expressed gratitude to members of both houses for voting in favour the new laws, which she said would protect the sector against the damaging effects of online piracy.
"For too long, this illegal activity has been threatening the livelihoods of thousands of workers throughout our sector," Ms Payne commented.
"Looking to the future, we now face the challenge of ensuring that the system outlined in the bill functions properly in order to allow industry to focus on developing new business models that can flourish without having to compete with illegal filesharing, downloading and streaming."
She said that only with such protection will the creative industries be able to continue investing in TV programmes, films, books, sporting events and music.
However, broadband provider TalkTalk has expressed dismay at the passage of the bill, which it describes as "draconian".
