I'd tie it more to the popularity of video games among adults(as I see adults, and younger people introduced to them by adults as the main driving force behind this board game resurgence), and the idea that there are always people looking to do things which are novel to them, and that things do not stay novel forever so there are people which shift to new or out of favor things which will be novel to them.

NBC I feel nailed it down with their tagline "If you haven't seen it, it's new to you"
