You may have noticed that we’ve changed the look of the player on
YouTube. You may even have noticed that we’ve been experimenting with
changing the look of embedded players too. Coming up on August 10, all
embeds will automatically be updated to the new "dark player". To read
more about the new "dark player", check out our blog post (http://
