Zero distribution costs. Zero marginal costs. Zero transactions.

Ben Thompson writing about Aggregation Theory:

Aggregation Theory is a completely new way to understand business in the Internet age. Business schools suggest that with the right frameworks, an executive can understand how to manage all kinds of problems: what happens, though, when many of the inputs to those frameworks are zero? (...) Zero distribution costs. Zero marginal costs. Zero transactions. This is what the Internet enables, and it is completely transforming not just technology companies but companies in every single industry.
