The show kept to a weekly schedule through mid-2002, after which the frequency with which new episodes were produced started to decline. New episodes were generally heard approximately twice a month through 2004, then roughly once a month in 2005. Dedicated author interviews became rare: from 2006-2011, "Hour 25" produced between 2 and 6 new episodes each year, usually centred around reports from Loscon, or readings of Christmas and/or Hallowe'en-themed science fiction stories. After 2008, episode lengths were consistently kept to under an hour, and Loscon reports were discontinued after 2010.
