By design, the news archive page is only going to display news stories posted in the current calendar year.

To have an important news story display once again on the archive page, simply adjust the publish date.

Tip: Be sure to include the News Archive Date Picker on your news archive page. The date picker provides visitors the option to travel back in time to view all archived news.
