Freakonomics blog
The authors started their own Freakonomics blog in 2005.
In May 2007, writer and blogger Melissa Lafsky was hired as the full-time editor of the site.[23] In August 2007, the blog was incorporated into The New York Times' web site – the authors had been writing joint columns for The New York Times Magazine since 2004 – and the domain Freakonomics.com became a redirect there.[24] In March 2008, Annika Mengisen replaced Lafsky as the blog editor.[25] The Freakonomics blog ended its association with The New York Times on March 1, 2011.[26]
Among the recurrent guest bloggers on the Freakonomics blog are Ian Ayres,[27] Daniel Hamermesh,[28] Eric A. Morris,[29] Sudhir Venkatesh,[30] Justin Wolfers[31] and others.
In 2008, Stephen Dubner asked for questions from the site's readers and then featured them in an extended Q&A on "Best Places to Live" with demographics expert Bert Sperling.[32]
SuperFreakonomics
In April 2007, co-author Stephen Dubner announced that there would be a sequel to Freakonomics, and that it would contain further writings about street gang culture from Sudhir Venkatesh, as well as a study of the use of money by capuchin monkeys.[33] Dubner said the title would be SuperFreakonomics,[34] and that one topic would be what makes people good at what they do.[35] The book was released in Europe in early October 2009 and in the United States on October 20, 2009.
Freakonomics radio
In September 2010, Marketplace radio announced the creation of a Freakonomics podcast hosted by Dubner and Levitt. It is available on iTunes and is aired bi-weekly on NPR.
Film adaptation
In 2010, Chad Troutwine, Chris Romano, and Dan O'Meara produced a documentary film adaptation with a budget of nearly $3 million in an anthology format by directors Seth Gordon, Morgan Spurlock, Alex Gibney, Eugene Jarecki, Rachel Grady, and Heidi Ewing.[36] It was the Closing Night Gala premiere film at the Tribeca Film Festival on April 30, 2010.[37] It was also the Opening Night film at the AFI/Discovery SilverDocs film festival on June 21, 2010. Magnolia Pictures acquired distribution rights for a Fall 2010 release.[38]
Freakonomics: The Movie was released in major cities with a pay what you want pricing offer for selected preview showings.[39] No report of the results has yet been published.
Freakonomics Consulting Group
In 2009, Levitt co-founded Freakonomics Consulting Group, a business and philanthropy consulting company which became The Greatest Good and is now known as TGG Group. Founding partners include Nobel laureates Daniel Kahneman and Gary Becker, as well as several other prominent economists.[40]
