Problem: American Idol:

The continuing decline influenced further changes for season 14, including the loss of Coca-Cola as the show's major sponsor, and a decision to only broadcast one, two-hour show per week during the top 12 rounds (with results from the previous week integrated into the performance show, rather than having a separate results show). On May 11, 2015, prior to the fourteenth season finale, Fox announced that the fifteenth season of American Idol would be its last. Despite these changes, the show's ratings would decline more sharply. The fourteenth season finale was the lowest-rated finale ever, with an average of only 8.03 million viewers watching the finale.

When did Fox announce the following season would be Idol's last?

A: May 11, 2015


Problem: Computer security:

In 1994, over a hundred intrusions were made by unidentified crackers into the Rome Laboratory, the US Air Force's main command and research facility.

The intruders were able to obtain classified files, such as air tasking order systems data and furthermore able to penetrate connected networks of National Aeronautics and Space Administration's Goddard Space Flight Center, Wright-Patterson Air Force Base, some Defense contractors, and other private sector organizations, by posing as a trusted Rome center user.

What did the 1994 breach of the National Aeronautics and Space Administration's Goddard Space Flight Center also give the crackers access to?
