Google have been known to throw new features, widgets and buttons onto sites to try and improve the experience and they could be doing the same with Youtube in an attempt to save it from the onslaught of Facebook Video and to affirm its position as the number one video sharing platform. Their latest experiment is ‘Cosmic Panda’, which is a new TestTube experiment open to all. Entering into the experiment gives you an entirely new view of Youtube, with the option to leave the experiment at any time.
According to Youtube’s own coverage of the experiment, this is largely a design change, bringing in a new viewing experience for the user. Features also include more options to customise your channel, which is a positive move for brands as the customisation features are currently fairly limited for standard channels.
From your favorite 
sports highlights and 
dance competitions to 
make-up tutorials, 
science experiments and 
great movies,  there’s a ton of great stuff on YouTube — over three billion views  worth per day by last count.  More and more, behind every great video is  a great Channel, and with our announcement last month that 
more of them are coming to YouTube, we want to make it easier for you to find and keep tabs of what you want to watch.
So, Youtube introducing a new homepage, Channel design and a fresh  coat of digital paint. Here are three ways these updates will improve  your life on YouTube:
1. A new homepage
   The YouTube homepage is your gateway to a vast entertainment universe.   To help you get more into YouTube, we’re making it easier to find and  follow great Channels when you arrive. On the left side of the homepage  you can create your own, personal, customizable YouTube Channel line-up.  Sign-in, or 
create a YouTube account.  Then you can browse recommended Channels; customize your homepage’s  feed; even link your YouTube account to Google+ and Facebook to see what  your friends are sharing. The new homepage feed we 
launched  earlier this year is now front and center on the homepage. You can  switch between feeds by clicking on different Channels on the left. 
For step by step instructions on using the new YouTube homepage, you can go to our 
help center.     
2. Simpler, customizable Channels
  Given the homepage’s new focus on helping you find and organize your  favorite Channels, we would be remiss if we didn’t update the look and  feel of the Channels themselves. Today we're launching an improved  Channel design focused on what matters most: helping users find great  videos. As different uploaders have different goals, we've created new  Channel templates to meet your needs whether you produce one video a  week or have thousands of videos for a fan to browse. Some partners have  even uploaded 
videos talking about the features, or 
giving tips on how they’re taking advantage of the new design. To learn how to opt-in to and test this new Channel design, check out our 
help center. 
3. A new overall design
  To bring the new homepage and Channels designs together we’ve also  applied a fresh coat of digital paint across the whole site. In July, we  
unveiled  an experimental design called Cosmic Panda. We’ve used your feedback to  improve our overall design, and today, we’re presenting a cleaner and  simpler YouTube, with a consistent gray background, bigger video  thumbnails and a more streamlined watch page.
