The U.S. Postal Service announced Wednesday that it plans to cut back to five-day-a-week deliveries for everything except packages, in an effort to stem its financial losses in a world radically re-ordered by the Internet.

“Our financial condition is urgent,” U.S. Postmaster General Patrick R. Donahoe said during a Wednesday press conference.
