Changing Digital Media Etiquette

I came across this clip today during my daily YouTube check-in. The clip is from Seinfeld, a popular sitcom in the 1990s. Even though Seinfeld is not that old, relatively speaking, it seems that the digital media etiquette that Jerry and George explain to Elaine in the clip has changed dramatically. Jerry and George are outraged that Elaine would make a serious phone call on a cell phone. Today, many people do not even have landlines, so their cell phones are used for mundane and serious matters alike! Most matters are simply discussed over text, reserving phone calls for only situations like the one Elaine is in. Perhaps it still holds true that serious matters should not be discussed on the street, but nevertheless, this joke is largely obsolete.
