For anyone that has not been to www.ted.com than I strongly recommend it. There is the most amazing range of information regarding science, religion, medicine and technology, and provides a very positive view of what the world will be like in the future.
One talk I just watched was http://www.ted.com/talks/what_we_learned_from_5_million_books.html, which discusses a new ability from goole at http://books.google.com/ngrams to search on the change in how regularly words appear in book.
I thought an interesting comparison would be whether the word Jehovah or Yahweh is more common. In the following graph it shows a huge rise in the term Yahweh and a fall in the term Jehovah over the last few decades. It appears that around the time of Russell there was a lot of talk about Jehovah, but now it is fading into obscurity.
There is limitations to the data, without knowing which books are included. Presently google has not included newspapers, etc either.
However, it does highlight that despite the Watchtower's best efforts, Jehovah is fairly unknown, and particularly in academic circles that are most likely to be publishing on the topic, Yahweh is the common term used. This diminishes the argument that though incorrect, Jehovah should be used in preference to Yahweh, as it is the better known form of God's name.
