DEPRESSION GLASS what is it?

Pictured are examples of  American made Depression Glass.

What exactly is Depression Glass?
I have gone to the Website of the National Depression Glass Association for their Definition for what Depression Glass is and I quote it word for word.

                         "National Depression Glass Association                                  "Preserving America's Glass Manufacturing Heritage"
                                The NDGA was ​Founded in 1974

"Definition"
Although the “Depression”​ years extended from late 1929 up to the start of World War II, the term Depression Glass refers to American - transparent glassware that was manufactured from the early to mid- 1920’s, through and around the end of
World War II.
Much of that time was considered the ​​“Great Depression”, but the glassmaking period extended out on both sides of the “Great Depression”

I have noticed that the Pressed Glass that was manufactured in Countries such as Australia, Czechoslovakia, England, France and Germany in and around the Great Depression is being associated with the name Depression Glass. 


With the National Depression Glass Association's definition in mind the name​ Depression Glass specifically refers ​only to American - transparent glassware that was manufactured in and around the time of the Great Depression.
