Recorded music trade revenues in Sweden have increased by 18% in the first nine months of 2009, following the majors' high-profile court victory over the Pirate Bay and the introduction of a new copyright law. There was also an 80% increase in trade revenue in the digital market while physical sales increased 9% by trade value, according to figures from IFPI Sweden. The increase in revenue is being attributed to new digital and physical offerings and the actions taken against piracy in 2009. Four new physical music retailers opened in Stockholm in 2009, while the Spotify streaming service claims 17% have signed up to the free ad-funded version in Sweden. The labels scored a victory in a Stockholm court in April, when four co-founders of the file-sharing BitTorrent tracker were found guilty of facilitating copyright infringement. They are appealing their fines and one-year prison sentences but, while the Pirate Bay still exists, it has gone through an abortive sale process and is now ditching its central Web tracker following separate legal threats in Sweden. New copyright legislation, the IPRED anti-piracy law, also received considerable media attention when it was introduced in April, which is based on the EU Enforcement Directive. Although it did not go so far as a three-strikes law, for the first time it did give copyright holders the right to obtain the IP addresses of those suspected of copyright violations from ISPs in order to take legal action. Research by GfK in June 2009 among consumers aged 15-74 found that 60% of file-sharers had stopped or reduced their P2P activity following the introduction of the IPRED law.
