Additionally, he broke the news of IBM's sale of its PC business to Lenovo, Boston Scientific's $25 billion acquisition of Guidant and Symantec's $13 billion deal for Veritas Software, and reported on News Corp.'s acquisition of Dow Jones and "The Wall Street Journal". Sorkin has reported on the Wall Street financial crisis, including the collapse of Bear Stearns and Lehman Brothers, and the government bailout of other major investment banks and AIG. He has also written about the troubled American auto industry. In 2007, Sorkin was one of the first journalists to identify and criticize a tax loophole for private equity firms and hedge funds. He first wrote about the topic in a column in March 2007, calling the tax treatment a "charade", and later wrote about it on the front page of "The New York Times". He has written at least a half dozen articles critiquing the tax practice by private equity firms and advocated for the government to end the loophole. In 2014, Sorkin wrote a series of columns criticizing American corporations for trying to lower their US tax bill by merging with smaller foreign companies in a transaction known as an "inversion". He also criticized the Wall Street banks that advised US companies to pursue such deals, describing the banks as "corporate co-conspirators". Sorkin called on the government to end the practice. On September 22, 2014, the Obama Administration changed the tax laws to make it more difficult for US companies to merge to avoid taxes. On the PRISM surveillance program and Edward Snowden situation, Sorkin said, "I would arrest him and now I'd almost arrest Glenn Greenwald, the journalist who seems to be out there, he wants to help him get to Ecuador." The next day, Sorkin apologized for the comment; Greenwald accepted, tweeting "Thank you: accepted & appreciated". Reviewing his record after his anti-Greenwald outburst, Matt Taibbi described Sorkin as "a shameless, ball-gargling prostitute for Wall Street". In October 2001, while a journalist at "The New York Times", Sorkin started "DealBook", a newsletter about deal-making and Wall Street. "DealBook" was one of the first financial news aggregation services on the Internet. In March 2006, Sorkin introduced a companion website published on "The New York Times", with updated news and original analysis throughout the day. In 2007, "DealBook" won a Webby Award for Best Business Blog and it won a SABEW award for overall excellence.
