The centerpiece lets creators in the [YouTube](/company/youtube) Partner Program designate playlists as shows directly in YouTube Studio: playlists of high-quality videos that share consistent themes and continuing stories can become episodic shows, complete with dedicated show pages and organized seasons, giving viewers a lean-back way to work through a creator's catalog on the big screen.

A four-digit code can now lock an account so viewing history and recommendations stay private on a communal TV, while a separate parent code prevents children from watching in signed-out mode. YouTube is also streamlining its QR-code sign-in flow and redesigning the casting and watch experience for kids' content.

The watch page is also being reorganized around longer sessions. YouTube is adding Shows and Podcasts tabs, a new access point for Shorts, and larger previous and next buttons designed to keep viewing moving from one video to the next, while musician pages gain a new-releases shelf that surfaces fresh drops.
