The document summarizes the DOJ's case against Apple regarding ebook pricing. It notes that Amazon originally used a wholesale pricing model for ebooks, which kept prices low, while publishers wanted higher prices. Apple then offered publishers an agency model, which essentially used resale price maintenance to set prices. Publishers conspired to switch to the agency model across all retailers, including Amazon, which led to increased ebook prices overall. The case was about the publishers conspiring to switch pricing models in a way that increased prices, not about resale price maintenance itself.
