Nirad Chaudhuri joined the news department of AIR in 1942 as a news commentator. His commentaries were mostly devoted to the war. His favourite themes were Churchill, who he greatly admired, and matters concerning the navy. The tonnage of warships was at his fingertips. But if in doubt, he would ring up his house and ask his sons to check the facts from his own reference books. He did not trust the news department's reference officer.
