From 1978 until 1983, Bergman was a producer, reporter and then in charge of investigative reporting at ABC News. He was one of the original producers of "&lt;a href="20/20%20%28US%20television%20series%29"&gt;20/20&lt;/a&gt;". In 1983, Bergman joined CBS News as a producer for the weekly newsmagazine "60 Minutes" and its lead correspondent, Mike Wallace. Over the course of 14 years, he produced more than 50 stories, ranging from exposes of organized crime, international arms dealing featuring Sarkis Soghanalian, then the world's main supplier to Saddam Hussein, and others to international drug trafficking in Venezuela involving the CIA to the Iran-Iraq and Persian Gulf wars. His five stories on California's then expanding prison system including the super max at Pelican Bay revealed everything from the horrors of solitary confinement to the staging of "gladiator" matches by its correctional officers. He also produced the first U.S. television interviews with Lebanon's Hezbollah leadership in the early 1990s, when they were considered the world's most dangerous terrorists.
