Combination Telephone and Autocar (Decade's End Outtake 1)

In the years after the invention of the telephone, when phone ownership became ubiquitous, did people say different things on the telephone than they would have otherwise before the invention of the phone, saying these things because of the phone? And then did these new things they'd said influence their off-phone life? How would we research this, or test our answers?

I wouldn't be surprised if new things were said, the device not just bringing ease of communication and an expansion of when to say it, but other differences - this being the first aural (as opposed to merely verbal, e.g. letters and books and scrolls, or symbolic [smoke signals, marks on trees, etc.]) form of disembodied communication. But also the ease and the expansion may also have given people an opportunity to say something that they wouldn't have said otherwise, or at least to say it more, to more people.

Think of automobiles: we know that their being adopted large-scale changed what trips people took and where they lived and whom they associated with.

(This in regard to the Internet and the Web: is it not just changing whom we "speak" to and when and how, but also what we say?)
