It was an oddly telling sign of the times: On Monday, when U.S. ambassador Suzi LeVine was sworn in, there was no printed copy of the U.S. Constitution on hand. Instead, LeVine was sworn in with a digital copy of the document stored on a Kindle Touch.

LeVine, the new U.S. ambassador to Switzerland and Liechtenstein, is now the nation’s first to take the oath of office with an e-reader. The U.S. Embassy in London tweeted out a photo of the event, captioned a “very 21st century swearing in.”

It’s no secret that print products are on the decline: as sales of e-books continue to rise, and paper books continue to fall, the size of the e-book market is expected to surpass print in 2017.

As Monday’s swearing-in ceremony demonstrated, words may be sacred, but the medium through which they are displayed certainly isn’t.
