10 Most Famous Jilted "Spouses" in Business

TechCrunch50's Michael Arrington and Jason Calacanis

Once upon a time there was a hugely successful tech conference called TechCrunch50, which was created by entrepreneur Jason Calacanis (pictured left) and TechCrunch's Michael Arrington. But after three years of conferences, some bad blood had brewed to a boiling point. The two men split ways for good when AOL bought TechCrunch, and Arrington decided to launch a new conference called TechCrunch Disrupt. Calacanis sued Arrington, claiming he had rights to profits from the AOL deal. Both men wrote public blog posts about split, Arrington calling Calacanis's actions "absurd," and Calacanis writing an entire post called "Why I'm Suing Michael Arrington." Calacanis eventually dropped the suit.
