Music will be another big focus for the company as it courts millennials. It will be extending a deal with Live Nation to broadcast music festivals, and will join iHeartMedia to broadcast other music events.
Electronic dance music will be the theme of "Ultimate DJ," produced by Simon Cowell. And Yahoo unveiled a new long-form series: a comedy called "The Pursuit" aimed at millennials in the digital age.
