It appears to me that this is a culturally dependent sort of thing, which is why I said it isn't "universally common" rather than it isn't common.
For instance, I'm a graybeard and in my entire life, I've only seen people do that a couple of times. And even then, the people being shown the media were putting up with it out of politeness. What people in my part of the US tend to do is tell the stories of the trip rather than show pictures. People here usually don't want to see pictures or video, they want to hear the stories.
