ReganBooks

Prominent ReganBooks titles include Jenna Jameson's How to Make Love Like a Porn Star, biographies by General Tommy Franks, professional wrestler Mick Foley, and radio talk show host Howard Stern, three different books on the Scott Peterson case, and those by political commentator Sean Hannity. Though ultimately owned by politically active Rupert Murdoch, ReganBooks disavowed any political agenda, publishing, for example, books both supportive of and critical of George W. Bush.

In August 2004, ReganBooks had three books on The New York Times Best Seller list, including the top two non-fiction positions, and the highest profit ratio at HarperCollins.

In 2005, ReganBooks announced plans to move from Manhattan to Los Angeles, making it one of the first major book publishers to move from the east to the west coast.

Controversy and closure

In November 2006, ReganBooks announced plans to publish O. J. Simpson's book If I Did It; publication was later cancelled by News Corporation chairman and CEO Rupert Murdoch. After the public fallout Newsweek reported, "Regan's meddlesome-free days are almost certainly over" and Murdoch will be "clamping" down on control.

On December 15, 2006, Regan was fired from HarperCollins, over antisemitic comments. The staff at ReganBooks were reassigned within the HarperCollins General Book Group. The New York Times reported that ReganBooks' offices were closed and "a stunned Ms. Regan was confronted by security guards who arrived with boxes and ordered her to leave." Regan sued News Corporation for $100 million for defamation over the antisemitism charge, asserting that it was "completely fabricated"; in January 2008 News Corporation settled the lawsuit and publicly stated, "After carefully considering the matter, we accept Ms. Regan's position that she did not say anything that was anti-Semitic in nature, and further believe that Ms. Regan is not anti-Semitic."
