spam filter gave the site a reputation as a "vortex of perversion". Around that time, specialized social media companies such as Twitter formed and began targeting users on MySpace, while Facebook rolled out communication tools that were seen as safe in comparison to MySpace. In addition, MySpace had particular problems with vandalism, phishing, malware, and spam, which it failed to curtail, making the site seem inhospitable. These have been cited as factors why users, who as teenagers were MySpace's strongest audience in 2006 and 2007, had been migrating to Facebook, which started strongly with the 18-to-24 group (mostly college students) and has been much more successful than MySpace at attracting older users. News Corporation chairman and CEO Rupert Murdoch was said to be frustrated that MySpace never met expectations as a distribution outlet for Fox studio content and missed the US$1 billion mark in total revenues. This resulted in DeWolfe and Anderson gradually losing their status within Murdoch's inner circle of executives, as well as DeWolfe's mentor Peter Chernin, president and COO of News Corporation, departing the company in June 2009. Former AOL executive Jonathan Miller, who joined News Corporation in charge of the digital media business, was in the job for three weeks when he shuffled MySpace's executive team in April 2009. MySpace president Tom Anderson stepped down while Chris DeWolfe was replaced as CEO by former Facebook COO Owen Van Natta. A meeting at News Corporation over the direction of MySpace in March 2009 was reportedly the catalyst for that management shakeup, with the Google search deal about to expire and the departure of key personnel (Myspace's COO, SVP of engineering, and SVP of strategy) to form a startup. Furthermore, the opening of extravagant new offices around the world was questioned, as Facebook did not have similarly expensive expansion plans but still attracted international users at a rapid rate. The changes to MySpace's executive ranks were followed in June 2009 by a layoff of 37.5% of its workforce (including 30% of its U.S. employees), reducing employees from 1,600 to 1,000. In 2009, MySpace implemented site redesigns as a way to get users back. However, this may have backfired, as users generally disliked tweaks and changes on Facebook.The Economist.
