In the article posted about gravitas the following numbers were reported:
"Media use of the word gravitas, according to search on Factiva, an
aggregator of news and information. First used in 1924, according to the
Oxford English Dictionary.
Year No. of times used
2000 2,644

Surely, they did not just Google this, did they?  How meaningless.  What
about duplications?  What about false positives?
