Panasonic launched a special 100 year anniversary page:
Panasonic was founded in 1918 by Konosuke Matsushita. That year, Panasonic introduced an improved attachment plug, which allowed people to power an electrical appliance from a light socket. Next was a double cluster socket that made it possible to power lights and appliances from a single source. Our principles of making life ever more comfortable originated from these small ideas.
Panasonic’s 100th anniversary is upon us. To address the changing times, we continue to develop the products of the future worldwide, always cherishing the principles our founder defined for us one century ago.
You can see some of their key products of their first 100 years on their page.
