Upon becoming commercial station WCBW  in 1941, the pioneer CBS television station in New York City broadcast two daily news programs, at 2:30 and 7:30 p.m. weekdays, anchored by Richard Hubbell. Most of the newscasts featured Hubbell reading a script with only occasional cutaways to a map or still photograph. When Pearl Harbor was bombed on December 7, 1941, WCBW , took to the air at 8:45 p.m. with an extensive special report. The national emergency even broke down the unspoken wall between CBS radio and television. WCBW executives convinced radio announcers and experts such as George Fielding Elliot and Linton Wells to come down to the Grand Central studios during the evening and give information and commentary on the attack. The WCBW special report that night lasted less than 90 minutes. But that special broadcast pushed the limits of live television in 1941 and opened up new possibilities for future broadcasts. As CBS wrote in a special report to the FCC, the unscheduled live news broadcast on December 7 "was unquestionably the most stimulating challenge and marked the greatest advance of any single problem faced up to that time." Additional newscasts were scheduled in the early days of the war. In May 1942, WCBW  sharply cut back its live program schedule and the newscasts were canceled, since the station temporarily suspended studio operations, resorting exclusively to the occasional broadcast of films. This was primarily because much of the staff had either joined the service or were redeployed to war related technical research, and to prolong the life of the early, unstable cameras which were now impossible to repair due to the wartime lack of parts.
