TF1 have used this music in one form or another since 1990, oui?
Compare and contrast with the Beeb's use of David Lowe's beeps since 1999, and ITV's use of Dave Hewson's rearrangements of "The Awakening" since 1995...
If we're gonna talk long-running news themes, then the Tagesschau has been using the same six-note melody (Hammond Fantasy) since 1956, and ZDF have been using their beeps (Morse code for 'heute') since 1973.
And in New Zealand, 1 News has retained the same motif in their various themes since at least the late 90s.
