An embargo worked—until a newspaper deadline intervened

For the Academy’s early ceremonies, the winners were not a secret from everyone in the room. The press received the results in advance under an embargo: an agreement to hold publication until a specified time. That arrangement suited newspapers, which needed time to prepare their stories, and it could preserve the surprise for readers—so long as every outlet honored the agreement.

In 1940, the Los Angeles Times published the results before the ceremony. Its readers could learn who had won before the awards were presented, turning a backstage press arrangement into a public spoiler. The problem was not that the results had been counted incorrectly; the system depended on keeping the list confidential, and that safeguard had failed.

The envelope made secrecy visible

The Academy’s response was to keep the winners concealed until each award was announced. Instead of relying on a promise not to publish a known list, the new procedure placed the result inside a sealed envelope, which was opened onstage. The envelope became both a practical barrier and a piece of theater: the audience could watch the same reveal as the nominees.

That change reshaped the ceremony’s suspense. A newspaper could no longer spoil a result simply by printing information it had received early; the winner was withheld until the presentation itself. The familiar pause before an envelope is opened grew out of a very ordinary vulnerability: a secret shared too soon is only as secure as the agreement surrounding it.
