Future announced existing cooking title Jamie magazine as the first external client for FutureFolio – an interactive tablet-edition production suite the company designed in-house to build its own magazines but which it is now also pitching as a service to peers and rivals. The publisher will soon launch a spin-off of its tech news website TechRadar as a weekly iPad magazine, sitting between the existing TechRadar rolling website and Future’s monthly T3 gadget magazine.
