The agency will create a brand campaign, due to launch in early 2016, across film, print, outdoor and online channels. It will work on a pro bono basis.
Although there is no incumbent on the account, The Big Issue has partnered with agencies in the past. In 2013, M&C Saatchi created a national print and outdoor campaign that promoted the magazine as a social enterprise scheme rather than a charity. The organisation has also worked with Bartle Bogle Hegarty.
The Big Issue depends on the income generated via magazine sales to offer its self-help opportunity to vulnerable people across the UK.
Larissa Vince, the director of marketing at Saatchi & Saatchi London, said: "The Big Issue is an iconic brand and a world-leading social enterprise. It’s a privilege to be chosen to work with them."
The Big Issue's marketing and communications director Lara McCullagh said: "We hope this campaign will highlight the still ground-breaking nature of what we do, and remind the public of the difference they can make by buying and taking the magazine."
