YouTube's kid-friendly app arrived earlier this year, delivering a library of age-appropriate content for younger viewers. Now, the streaming software is moving beyond mobile devices. YouTube Kids is now available on your television, streaming to Chromecast, Apple TV, game consoles and smart TVs. There's also new curated playlists from the likes of National Geographic Kids and tools for parents that help you learn the app and tweak the password. Perhaps most importantly, you won't have to give up your phone or tablet when junior wants to catch up on the latest episodes.
