Perfect Market, an Idealab-incubated company offering publishers tools to monetize archival content, has raised a $15.6 million from Trinity Ventures, Rustic Canyon Partners, Square 1 Bank, and founding investor Idealab.

This notion of “lighting up” dark content for this way has been big for awhile — newspapers in particular have recognized the lost search revenue because their archive content has not been readily available.
