Oh, how the world has changed in a hundred years.

The Great War was fought with no one on the home front really knowing what was going on. With an ocean between, letters from Europe would take weeks to reach loved ones in Canada.

By World War II, news came via radio reports and newsreels at the movies.

During the war in Vietnam, reporters on the ground were able to send live reports and video so people were watching Walter Cronkite to see the day's news.

The Gulf War brought live video via satellite from the front lines, including incoming scud missiles. By the Afghanistan and Iraq wars, email was in common use.

And today, people in Ukraine are live-streaming from their smart phones, showing up close the advance of the Russian army. Face-time, Facebook, Tik Tok and Instagram have brought this war to the palm of our hands. It truly has become personal.
