Ordering "Networking" Cards - Huh?

Saw this Vistaprint online ad on Pandora. What caught my eye and made me click on it was that it was advertising for 250 free "Networking Cards". Not "Business Cards", but Networking Cards. In today's day and age, business seems to begin with some sort of networking "event", whether it be social networking discussion boards, invitations or live networking events. The fact that Vistaprint is advertising cards, that are traditionally known as Business Cards, as Networking Cards is quite an evolution of this print medium. How can you take your product/service and re-brand it to meet a different target market or "event"?
