YouTube for iOS and Android is being updated with a new homepage starting today, replacing the small thumbnails that offered up recommended videos with a single in-line content stream that serves up ranked recommended videos based on an improved algorithm.
Whether you want to watch hilarious sketch comedy, your favorite vlogger, new let's plays, or music videos, you should be able to see new videos you love every time you visit YouTube--right on your homepage. Starting today, when you open the YouTube app on your iPhone or Android phone, you'll experience a redesigned Home, with a clean and simple format that invites you to discover and enjoy.
With the single stream, video previews on the home screen are larger and easier to scroll through to find interesting content, much like the trending videos displayed in the Trending tab. The new algorithm, which is based on deep neural network technology, is able to refresh videos on a more frequent basis so content displayed is kept up to date and it's able to present content that's more relevant to each user's tastes.
According to YouTube, people who have tested the new system spend more time watching fresh videos and content from their Subscriptions.
