LOS ANGELES — Rapper-producer Pharrell Williams is expanding his focus to include a new cable TV network aimed at the online generation.

Karmaloop TV said Monday that Williams has been named creative director for the network scheduled to launch later this year. Karmaloop will feature original productions along with movies that have shaped the 18-to-34-year-olds who grew up with the Internet.

The Grammy-winning Williams, who has created hits for Jay-Z, Britney Spears and other stars, will have a significant equity position in Karmaloop TV, according to the company.

Williams, frontman for the rap-rock trio N.E.R.D. and half of the production duo The Neptunes, said the “progressive youth culture” is underserved by what’s available in the marketplace.
