4iP is a three year, £20 million fund by Channel 4 to support digital media projects across the UK that help people improve their lives. It will fund websites, games and mobile services with innovative ideas. Some areas of interest include digital democracy, amplifying underrepresented voices, and tools to encourage civic participation. Successful projects will be participatory, scale well, and be sustainable without ongoing financial support from 4iP. Examples of funded projects are described.
