on a different angle, "smartphone" first occurrence in 1998, which matches with wikipedia reporting it in 1997 from Ericsson blob:http://chronicle.nytlabs.com/d4661696-f25d-47be-8a83-8996420...

No pedophile or paedophile before 1986? http://chronicle.nytlabs.com/?keyword=paedophile.pedophile

I'm vaguely interested about why aluminium has peaks between 1955 and 1970 (although it's always much lower than aluminum) http://chronicle.nytlabs.com/?keyword=aluminum.aluminium

A couple of words show small peaks from 2010:

Something I've noticed (anecdotally) over the past few years in the USA is the switch from the term 'cell phone' to 'mobile phone'. Here in the UK we've used the term 'mobile phone' exclusively I think for the past 20 or 30 years.

It's not as clear as other examples, but you can certainly see a visible trend in the last decade: http://chronicle.nytlabs.com/?keyword=Mobile%20phone.Cell%20...

Kind of amusing to see the archaic term "wireless" start to recover its popularity around 1990.
