Answer
In 1954, Edward R. Murrow's television exposé on Senator Joseph McCarthy's communist-hunting tactics marked a turning point in the fight against McCarthyism. Murrow's scathing criticism, backed by compelling evidence, greatly eroded McCarthy's public support and signaled the beginning of the senator's downfall. This pivotal moment marked a significant shift in public perception and played a crucial role in curbing McCarthy's influence and the broader anti-communist fervor that characterized the era.
