However, since the FTSE-100 is 90% of the UK stock market anyway, these other indices are small fry by comparison.
The Gazette litteraire (1764-1766), which had Voltaire, Diderot and SaintLambert among its editors, was intended to swamp the small fry by criticism; the Journal des dames (1759-1778) was of a light magazine class; and the Journal de monsieur (1776-1783) had three phases of existence, and died after extending to thirty volumes.
Of course all of this is small fry compared to the quirky headliners.
