Final answer:
Edward R. Murrow is best known for his live World War II radio broadcasts from London, which marked a significant moment in the evolution of radio news, and for his influential television journalism that followed.
Step-by-step explanation:
Edward R. Murrow is best remembered for his incisive journalism during a critical time in history. His accounts from London during World War II provided live coverage during Germany's aerial bombing of the city, which played a significant role in shaping radio news. Murrow's reports were informative and contained news commentary, often under guidelines to protect military operations. His transition to television with shows like See It Now further solidified his status as a pioneer in broadcast journalism, bringing news into American living rooms with immediacy and a sense of community.
In contrast to Murrow's work, it was Walter Cronkite who was known for reporting during the Vietnam War, a conflict often remembered as the first "living-room war" due to the televised coverage that brought stark images and realities of war into American homes. Edward R. Murrow's legacy, however, is more closely associated with his groundbreaking radio broadcasts from London and his subsequent television journalism, which shaped the media landscape for decades to follow.
