How can I find a video I just viewed but did not save or subscribe to?

If you're logged on to your YouTube account:

1. Click:  Account
   
2. Find the blue section of the Account Overview page.
   
3. Find the first column called "My Videos"
   
4. Click:  History
   

If not logged on:

• Check your Internet browser's History
  
  Generally, they are grouped on by day and they may also be grouped by the site.  Expand each grouping when appropriate.  Unless you have enabled a setting to clear your history, the video you watched should be here.
