As Chuck is a comedy series with strong ties to both geek and tech-culture, and also part of the "spy" genre, some emphasis is placed on technology within the show. Technologies in the show usually drive the plot (most notably the Intersect), but some gadgets are directly for comic effect (tennis ball grenades). Some of the devices in the series are accompanied by a nod to pop-culture, such as the GLG-20 listening device. There are multiple references made to James Bond in particular.
