"narrative history series"

Radio Four controller Gwyneth Williams brings news of schedule changes. The World at One is being extended by fifteen minutes with the "narrative history series" (The Making of Music, A History of the World ...) moving to fill up the hour and a regular science slot on Tuesday mornings.  This American Life's poor cousin Americana axed.  The methodology seems to be to bring the channel more in line with other BBC networks in offering recognisable blocks of content, certain types of programme appearing in regular places.
