Question: When was the mini-series Centennial first broadcast? — Anthony J., Leeds, West Yorkshire, England

Televisionary: NBC first broadcast the 24-hour epic from October 1978 to February 1979, Anthony. Then it reran it the following year because an actors' strike turned the programming faucet off for a while.

As you and other fans may well know, the sweeping tale, which followed the doings in a piece of territory near the Rockies from the late 1700s through the 1970s, helped employ a large chunk of the Screen Actors Guild membership. (Well, not really, but you get my drift.) Stars included the aforementioned Richard Chamberlain (who apparently was requird by law to appear in every network mini-series of the time), Robert Conrad, Raymond Burr, Gregory Harrison, Chad Everett, Alex Karras, Richard Crenna, Anthony Zerbe, Barbara Carrera, Michael Ansara, Mark Harmon, Timothy Dalton, Lynn Redgrave, David Janssen, Andy Griffith, Sharon Gless and Robert Vaughn.

It's worth pointing out that author James Michener, upon whose novel the show was based, said at the beginning of the mini-series that his creation was intended to remind people that what they do to the land they live on impacts future generations. It's a shame more people don't keep that in mind nowadays.
