, almost all of the 1979–2001 "second series" episodes are still in active rotation on a number of PBS stations. The only exception is the week-long "Conflict" series (episodes #1521–#1525), first aired during the week of November 7–11, 1983. The series/story arc covered the topics of war, bombs, and an arms race, and was created in response to the Invasion of Grenada, and the 1983 Beirut barracks bombings. The "Conflict" series was last aired on PBS during the week of April 1–5, 1996.
