A social-media promotion this season for "Chuck" [powered by Thingfo] gave David Paul of Turlock, Calif., the chance to have his photo included in one of the title character's flash-of-brilliance sequences in the May 25 finale.

"What better way to spread the word about our shows then with the help of our loyal fans,"stated Adam Stotsky, president, NBC entertainment marketing. He calls the effort a "win-win opportunity" that broadens the shows' visibility.

Added Vivi Zigler, president, NBCU digital entertainment, "Fan It is a natural extension that will keep users engaged with their favorite shows even when they're not on television."
