A show genre that is shamelessly and purely based around nostalgia. The format is simple, cheap, seldom varied, and generally goes like this: (Stock footage of people participating in [fad]) And so on, and so on. Replace 'fad' with 'toy', 'hairstyle' or 'type of music' as needed. Compare with Anyone Remember Pogs, Top Ten List. Often invokes the Nostalgia Filter. Can potentially count as Narm when taken too seriously.
