d-commerce

A form of e-commerce by companies that sell news, documents, subscriptions, or any other content that can be delivered digitally over the Web.

Under the ultimate "pay as you go" model, a "d-commerce company" acts as an electronic middleman: Users establish an account with a d-commerce company to purchase content from a variety publishers, which is easier because they give out their credit card number once instead of to a multitude of Web publishers. The d-commerce company, in turn, handles the billing, collection, refunds, and other payment processes for the publisher.

D-commerce is considered a form of e-commerce because money is exchanged for a product or service that exists "electronically" (in this case, "digitally").
