#BlueMonday - How the brands tried to spread joy on social media

It's officially Blue Monday "the most depressing day of the year".

#BlueMonday was trending on Twitter in the UK on Monday (19 January) with brands quick to participate in the discourse with social media users on their gloomy winter commutes.

The term "Blue Monday" was first coined in 2005 by a PR agency working with Sky Travel in a bid to sell more holidays during the post-Christmas period, according to Dan Grech, email marketing manager at the Net-A-Porter Group.

The story was circulated to the media along with research - including a “formula” - proving the day’s alleged depression factor. Below are the brands' attempts to spread some smiles - and promotions - throughout Twitter.
