These programs are an invaluable part of modern graphic design used in many businesses and by many private artists and professionals.
Adobe has a prominent place in the computing industry due to their purveying .pdf readers, visual manipulation software and other pivotal pieces of software. This has led to the wide dissemination of their programs and to the general standardization of those programs in many industries.
Online marketplaces like Adobe's provide the simplest route to accessing these programs in new and used condition. When a physical copy is needed it can be ordered simply and shipped to a given location so that it can be installed and, if necessary, uninstalled and transferred to a new machine. This provides quite a bit of versatility.
