The commas are used correctly.
The one after era is used to indicate the end of the sub-clause. The rest are used for itemization (listing comma).
Note that the comma used before and is called the Oxford comma. This type of comma is used before a conjunction (usually, “and” and “or”) in a list of three or more items before the last term. The Oxford comma is typical of American English. In British English it is sometimes omitted.
