BEVERLY HILLS, Calif. • Do you know "The Karate Kid"?

"I don't know anyone who doesn't know 'The Karate Kid,'" says Susanne Daniels, head of digital content for YouTube. Fans have kept the movie franchise alive with "clips, tributes and related content," the streaming network says.

Thus "Cobra Kai," a 10-episode "Karate Kid" sequel reuniting Ralph Macchio and William Zabka, due next year on subscription service YouTube Red.

Macchio and Zabka return as Daniel LaRusso, the underdog, and Johnny Lawrence (Zabka), the bully, last seen at the 1984 All Valley Karate Tournament. The new comedy, set three decades later, finds a desperate Johnny reopening the Cobra Kai karate dojo, reigniting his rivalry with Daniel, now successful but minus his mentor, Mr. Miyagi (the late Pat Morita).

The creators of "Cobra Kai" are Josh Heald ("Hot Tub Time Machine") and Jon Hurwitz and Hayden Schlossberg ("Harold and Kumar").

YouTube Red, with original scripted programming and streaming music, costs $10 a month. Daniels told TV critics Friday that she is amused by jokes that a lot of people think YouTube Red is a porn channel.
