Each morning all throughout the federal government, offices are receiving thousands of copies of multiple newspapers and magazines. The vast majority of these subscriptions can and should be eliminated; only the agency public affairs office might possibly require these publications. These public affairs offices in many case already employ the best practice of compiling relevant news stories for that agency into an electronically distributed compilation (e.g. DoD Early Bird, State Dept Press Clips).
By cancelling delivery to seemingly every federal office, the government can save thousands of trees and millions of dollars, as well as avoid any perception of preferential treatment towards the companies whose papers are normally purchased.
