You may already be sick of the name, but Black Friday has helped buoy declining newspaper advertising departments to the tune of nearly £5m, becoming by some distance the biggest weekday ad take of the year. Advertisers spent almost 80% more than on a typical Friday, with the Sun, Daily Mirror and freesheet Metro the biggest winners. However, due to declining circulations across the market, this year’s estimated GBP4.7m advertising haul is down on the last two years.
