Do entice the viewer
Nokia Designs has a smart strategy at work in the subscriber section of YouTube.

Nokia is one of the few brands associated with cellular service that has broad appeal to consumers, and they’ve isolated a major part of that reason-- elegant and cool simplicity in their design.
That’s why the Nokia Design section works so well here, not just because it shows what’s happening now; it also entices consumers toward regarding what’s going to happen next, inviting them to engage with the brand later and building excitement through the viral opportunities.
This is very smart stuff.
