Free papers pioneer new ad formats

City AM is offering advertisers the chance to use a variety of different shapes and different page positions from next month. The financial paper distributed free in London every morning will allow triangles, pyramids and a series of "floated" positions within editorial content. It is known that News International's new giveaway title, thelondonpaper, has shown a circular-shaped ad format in one of its dummies. (Via Brand Republic)
