The University of Warwick’s Andrew Oswald and his team compared survey data on the life satisfaction of more than 900,000 citizens of 27 European countries from 1980 to 2011 with data on annual advertising spending in those nations over the same period.

Their conclusion: Advertising makes us unhappy.
