How do you erase your history on an ipod touch?

for safari history go to settings then safari and theres a button to clear history, data and cookies to clear the ipod of everything go to setttings and then general, go to bottom and then pick reset you may not have this if you are running on a much older ipod IOS

Go to safari, then go to bookmarks. It'll say history and click on it, then click on where it says clear. The bookmarks is the book looking thing at the bottom of the iPod when you're on safari. It's next to the plus button. And that's how you delete your history.

Can you be more specific, do you mean Youtube history?
