Did... this... really happen? I hope not. I imagine a huge screen above and behind the priest where the guests could see the couple's phones (or laptop screens?) as they change their FB status. Hah, that's the perfect imagery, Zuck's creation being displayed on the altar, in lieu the cross.
Searching for examples on YouTube just gets me junk about bridezillas or "bride reads cheating fiance's text instead of vows".
Maybe in this alternate future, weddings are made official by clicking "I agree" after scrolling through the EULA, formerly known as prenup.
