We rang in the New Year with breaking news from everywhere.

We grabbed a front-row seat to the most exclusive events and conversations.

When people talked about things as dense as politics and as simple as love.

We shared moments of mourning, reflecting, commemorating.

We were present at the biggest spectator events — and a complex medical procedure.

The world spun, events surprised us, and a missing creature turned up safe.

From a boat in a canal to a plane on a runway, first-hand accounts revealed the biggest stories.

Some viewers live-tweeted TV programs; others imagined live-tweeting an event half a century earlier.

We discussed winners and losers in elections, selections, and for awards.

We absorbed doings from global issues to the World Series.

Tragedy, triumph and tributes brought people closer.

As the year comes to a close, anticipation builds anew for what’s next.
