Difference between Norton Security & Norton 360?

A simple question - I hope.

Is there a difference between Norton Security & Norton 360?

I've just received an E_Mail from Norton offering a 75% discount on Norton Security but I'm used to Norton 360.  Norton 360 isn't listed on the list of Norton products so I can't research this myself.  I wonder if they've just renamed 360 to Security.

 

Regards and thanks.
