Prompted by online developers’ need for quick cash infusions, CPB is offering Public Media Innovation grants of $5,000 to $20,000 for stations to experiment in emerging media platforms, with target audiences. Round 1 applications, due June 18, must relate to the 2008 national, state or local elections. Round 2 will be open to other projects. Details are online. Mark Fuerst is project director, publicmediainnovationsgmail.com.
