Camden Conference will present Mac Deford and Tom DeMarco in their 13th 100-minute History Roadshow presentation at 6 p.m. on Thursday, January 23, at Portland Public Library; at 6:30 p.m. on Friday, January 24, at Rockport Opera House; and at 2 p.m. on Sunday, January 26, at University of Maine Hutchinson Center in Belfast. No reservations are necessary; donations will be appreciated.

Consistent with the 2020 Camden Conference theme, Deford and DeMarco will present “The Front Page: A History of the News from Town Criers to TV.” The two will discuss the contributions of Jean-Paul Marat, journalist of the revolution; Benjamin Day, the first media tycoon; William Lloyd Garrison; Frederick Douglass; Edward R. Murrow and the “Murrow Boys,” James Thompson Callender, America’s first investigative reporter and the first one to pay for practicing that trade with his life; and more.

DeMarco is the author of 16 books and a principal of Atlantic Systems Guild, a technology think tank. Deford is a retired Foreign Service officer, worked with Merrill Lynch International, and has been a regular columnist with The Free Press.

The talk 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.
