NEW YORK (AdAge.com) -- "Heroes" creator and executive producer Tim Kring believes mobile phone apps provide powerful new tools for TV writers of the digital age. At Ad Age's recent Digital Conference, he discussed applications he is creating for Nokia's new Ovi apps store. The original version of this program incorrectly said those new apps would involve "Heroes" content. But they won't. Instead they will be original new works. Among other things, the downloadable phone programs will empower users to become part of Kring's new programming.
