Product of the Year

What are the products of the year - historical mark products - what would you put in a time capsule? Put a reason under a picture of each item.

A product that I would put in a time capsule would be a Rotary Dial Phone.

 Though it's really old, but it can be really reliable. If the electricity is out because of the pole being fixed or needed to be fix, you can still use the Rotary Dial Phone. It is not powered by an electric company, so rather than using AC (alternative current) it using DC (direct current).
