Amazon Video
Customers of Amazon Video can stream on the web using an HTML5 player (supported in Chrome, Firefox, Internet Explorer 11, Edge, Safari and Opera).
Internet Browser (Nintendo 3DS)
On the New 3DS, a new video player is integrated into the browser. It can play back both 2D and 3D Videos on webpages which supports HTML5. This eliminates the need for the dedicated YouTube app on the new 3DS.
