Since their introduction, telephones have evolved drastically. Phones now blur the lines between telephone and computer, and the social norms regarding usage in public have morphed along with them. So what exactly is “correct” when it comes to modern-day smartphone etiquette? In a new study by Pew Research Center, 77% of adults felt it was OK for people to use their phones while walking down a street, 38% are OK with people using them at dinner and just 5% think its fine to use phones at a meeting. Compare that to the rampant rudeness of telephone users back in 1907, as declared by a New York Times reporter.
