What was the purpose on inventing the paper video disc.

For advanced HD (high definition) storage of videos. Also, because production of such a product is cheaper and safer for the environment, being made with alternate materials than conventional ones.

Explanation: The company Sony partnered with Toppan Printing (a company from Japan) to make a different sort of disc with the same quality of that of a Blu-ray disc. The reason for the invention of the Blu-ray disc was to create better data usage because the Blu-ray disc stores data using a blue laser rather than a red laser like normal disc. However since, Blu-ray discs contain a limited material such polycarbonate plastic which is derived of oil, Sony decided to make a paper disc instead. Using paper instead of polycarbonate plastic, they made a product that was both recyclable, less harmful to the environment and capable of achieving the quality of that of a Blu-ray disc. The materials are also cheaper to obtain and make.

Hope this helps! :)

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
