What does the meaning of Norton Internet Security 2012 logo on NIS 2013 Box?

[Pekky]

Hello guys,

 

I've bought Norton Internet Security 2013 Box and then I saw this logo on upper right corner of the box.

 

 

I just wondering what does this logo of 2012 mean? It isn't a version of the NIS I just bought, right?

 

Thank you.
