The rising interest in IT governance is partly due to compliance initiatives (e.g. Sarbanes-Oxley (USA) and Basel II (Europe)), as well as the acknowledgment that IT projects can easily get out of control and profoundly affect the performance of an organization. The Sarbanes-Oxley Act of 2002 (Pub. L. No. 107-204, 116 Stat. 745), also known as the Public Company Accounting Reform and Investor Protection Act of 2002 and commonly called SOX or Sarbox; is a United States federal law signed into law on July 30, 2002 in response to a number of major corporate and accounting scandals including those affecting Enron, Tyco International, Peregrine Systems and WorldCom. These scandals resulted in a decline of public trust in accounting and reporting practices. Named after sponsors Senator Paul Sarbanes (D- MD) and Representative Michael G. Oxley (R-OH), the Act was approved by the House by a vote of 423-3. Source: http://en.wikipedia.org/wiki/Sarbanes-Oxley_Act
