Most of you have noticed by now that YouTube has made some dramatic changes to its site. The video screen now accommodates widescreen (16:9 aspect ratio for HD) and the “Watch in high quality” links will also include “Watch in HD.” This is pretty good news in terms of the direction the site is heading in since competing video sites like Hulu are also showing videos in high definition. YouTube says upcoming filtering options will include the ability to search HD videos so users don’t have to rummage through search results for them. In addition to HD videos and the ability to filter them, YouTube will be adding three new landing pages: youtube.com/music, youtube.com/news and youtube.com/movies, making categorization and search that much easier. In all, the Internet’s leading video sharing site is only getting better and hopefully it will start monetizing its content a bit more efficiently to appease investors who have been bugging Google since it acquired YouTube in back October 2006.
