§Note that many NBC affiliates chose not to carry the first fifteen minutes of the show during this period, instead preferring to air a local newscast from 11 p.m. to 11:30 p.m. As of February 1965, Carson refused to host the first 15 minutes of the program, preferring to wait until the full network was in place before delivering his opening monologue; Ed McMahon hosted the program's first 15 minutes instead. This persisted for nearly two years, until the show's start time was finally adjusted to 11:30 p.m. in January 1967.
