Phones haven't made TVs at home obsolete, but they've definitely made an impact at airports and planes. There are fewer seatback entertainment systems anymore as aircraft have wifi and stream movies to personally owned devices or rent out tablets. Fewer people look at the departure and arrival list because that information is duplicated on the airline app on their phone, which also has their boarding pass. No one is watching CNN on the TVs at their gate; everyone's looking at their phone.
