The Materiality of the Digital

From Mediated Memories, by Jose van Dijck, pg 46-47:

Digital objects, such as photographs, are considered by many to be immaterial because digits are invisible and they can be endlessly manipulated until a final format (printed photograph, music CD) “materializes.” However, to understand the digital as immaterial is as erroneous as the idea of analogue mediated objects being static reminders of past experience. Layers of code are definitely material, even if this materiality is different from the analog objects that we are used to and that are still very much part of our personal cultural memory.
