Record labels manage the production, distribution, marketing, and copyright protection of music recordings and videos. They search for and develop new artists while maintaining contracts with recording artists. Sony Music Entertainment is the second largest global recorded music company, controlled by Sony Corporation of America and headquartered in New York. In 2012, Sony Music filed charges against IsoHunt claiming the website was designed to profit from rampant copyright infringement. EMI Group is the fourth largest music company and family of record labels, headquartered in London with a major publishing arm. However, EMI faced financial troubles and $4 billion in debt.
