It consists of PBS member station WILL-TV (digital channel 9, virtual channel 12) and National Public Radio member stations WILL (580 kHz) and WILL-FM (90.9 MHz).

The WiLL brand was a marketing approach shared by a small group of Japanese companies who decided to offer products and services that focused on a younger demographic from August 1999 until July 2004 in Japan. The companies that participated were the Kao Corporation (a manufacturer of personal hygiene, household detergents, and cosmetics), Toyota, Asahi Breweries, Panasonic, , Ezaki Glico Candy, and (an office furniture and stationery manufacturer). Toyota also engaged in a similar "youth oriented" approach in North America, with the Project Genesis program. This selective marketing experiment reflected a Japanese engineering philosophy called Kansei engineering, which was used by other Japanese companies.
