Generation does not consider the number of reproductions made from the same source. Rather, it describes the number of times a new source is made from a copy. A print made directly from a negative is described as a first-generation copy. A reproduction from that print is a second-generation copy, and so forth. – Generation is often used to describe major evolutions in technology. - https://definedterm.com/generation_also_copy_status
