The Camden Conference will present a talk by Peter Imber, “Ten Reasons for the Decline of the Evening News,” at Rockland Public Library on Thursday, December 5, at 6:30 p.m. Imber worked for 26 years as a producer for ABC News, covering the Los Angeles riots in the wake of the Rodney King beating, the O.J. Simpson trial, the Columbine school shooting and other major news stories. He retired to Maine in 2010 and is a past president of the Camden Conference. Fifty years ago, CBS Evening News averaged nearly 30 million nightly viewers. Today, the three major TV networks’ evening news broadcasts have a combined audience that is half that number. Imber will explain how this situation evolved, examining the history of TV news, the impacts of technology, the influence of corporate control of networks, the rise of cable news and the growth of social media as a news source. This event is presented in anticipation of the 33rd annual Camden Conference — The Media Revolution: Changing the World, February 21 to 23, to be held live at the Camden Opera House and livestreamed to the Hutchinson Center in Belfast, Strand Theatre in Rockland, and Hannaford Hall in Portland. The mission of the Camden Conference is to foster informed discourse on world issues. For more information, visit camdenconference.org or call 236-1034.
