Creator Aaron Korsh, whose "Notes from the Underbelly" sitcom was canceled during the 2007–2008 Writers' Strike, wrote a spec script intended to be a "half-hour "Entourage"-type based on my experiences working on Wall Street." He later realized that the project should have hour-long episodes. Korsh and his agent took the script to several production companies and wanted to give the script to Universal Media Studios. However, Korsh found it odd that the studio did not want to sell the script to NBC, the network the studio typically worked with. Korsh's agent convinced USA Network executive Alex Sepiol that although the series was neither a procedural nor what the network typically did, he would like the characters. Sepiol approved of the script, and by then, Hypnotic Films &amp; Television signed on to the project. The team pitched the script to USA, which bought the script after the pitch. Korsh did not pitch it to anyone else. When rewriting the script, Korsh made only small changes to the first half-hour, up to when Mike is hired. Originally, Mike did not take LSATs for others and only pretends to have attended Harvard, as opposed to pretending he attended Harvard and has a law degree. Korsh noted that there is no degree or test needed to work on Wall Street and be a mathematical genius, unlike the bar examination in law. He decided to "embrace" this difference and change the premise.
