That Was Then, This Is Now is a BBC Radio 2 history based comedy sketch show co-written and presented by Richard Herring.
The series also features musical interludes from a band, fronted by Christian Reilly, who went by a different name each week.

Each show would contain sketches based on historical events, the anniversary of which would be around the date of transmission.
A running joke in the second series was that Radio 2 had commissioned it so that the final epsisodes went out at the same time of year as the first episodes of the first series, meaning that exactly the same anniversaries were coming around as for the first.

The earlier part of the series also featured a running joke as to whether such a show should acknowledge the anniversary of the September 11 attacks, and debate as to whether ignoring it would be more offensive than not ignoring it.
