As the video’s creator says:

Our love affair with crisps still burns brightly, so I thought it was time for a video dedicated to the humble crisp, in particular those favourites of yesteryear that are sadly no longer available. Get ready for a nostalgic jaunt back to the tuck shops and newsagents of the past as we remember Lost Crisps and Snacks of Days Gone By.
