NBC host Chuck Scarborough announced his plans to retire from the network during a Thursday evening broadcast after over five decades in journalism according to NBC News.  "The time has come to pass the torch," he told viewers.  "Fifty years, eight months and 17 days after I walked into the door here at the headquarters of the National Broadcasting Company, I will step away from this anchor desk." Over the course of his career, Scarborough has reported from cities around the world, authored three novels and earned a total of 38 local Emmy Awards, among other accomplishments, according to his biography.  His last official day will be Dec. 12.  “There is only one word: gratitude,” Scarborough wrote in a statement.  “Our WNBC viewers welcomed me into their homes for more than 50 years, trusting me to present the news free of any agenda, faithful to the fundamental principles of accuracy, objectivity and fairness—and to bring them vital, timely information during our darkest and brightest hours. That has been an extraordinary honor.”
