The Guardian News and Media (GNM) has appointed BBH for a new brand campaign, which will take place in early 2012.

Adam Freeman, GNM's executive director for commercial, said: "The quality of our journalism and our unique, open approach to publishing on the web have brought us a record global audience of more than 50 million unique browsers. We've also seen a number of highly successful digital launches, including apps for iPad and Facebook. It's a great moment to make a significant investment in our brand.

"We're looking forward to working with BBH on an integrated brand and marketing strategy as we build on our growing international reputation as an open, independent and digital-first media organisation."

Jason Gonsalves, managing partner at BBH, said: "At BBH we believe that creativity and a commitment to difference is what enables businesses to outperform competitors and redefine their categories. That's why we are so excited to be working with a pioneering organisation like the Guardian, to give voice to the brand at a time when it is evolving into a digitally powered, global business."
