Introducing Bad Bets, a new podcast series from The Wall Street Journal that unravels big-business dramas that have had a big impact on our world. We begin with the Enron saga. In the 1990s, the U.S. energy company was a darling of Wall Street. But after the Journal uncovered monumental corporate fraud at Enron, the company quickly descended into bankruptcy, compromising tens of billions of dollars and thousands of jobs. Now, on the 20th anniversary of Enron's collapse, this story is as relevant as ever. This season on 'Bad Bets', Journal reporters John Emshwiller and Rebecca Smith talk to key players who witnessed Enron's downfall from the inside, including a whistleblower who speaks on the record for the first time.
