Goodman continued his fast rise throughout the late 1930s with his big band, his trio and quartet, and a sextet. On January 16, 1938, his band made a famous appearance at Carnegie Hall. By the mid-1940s, big bands became less popular. Some reasons for this are that talented musicians were entering the military or getting better-paying factory jobs, gasoline and rubber rationing during WWII, two long musician recording strikes, and the rise of popular singers like Frank Sinatra.
