Is it e-Learning or eLearning?

I just saw Gabe's post E-Learning: Will We One Day Lose the E? that discuss my post eLearning or Learning? - More to It. One of the things that Gabe tells us is:

Based on Google queries, e-learning (about 200,000,000 results) takes the cake over elearning (about 14,400,000 results) in 2007. So the world seems to like the hyphen.

My results are a little different but there certainly are more pages out there that have the hypen.

However, I actually believe the trend is more to drop the hypen. To back me up I went to Google Trends to see what the trend is for people searching. Here's what I saw:

Worldwide -


"eLearning" has almost caught "e-Learning" in terms of what people use in their searches.

In the United States -


"eLearning" is used more often in searches than "e-Learning" ...

Bottom line, like Gabe mentioned e-mail got shortened to email, I would be surprised if eLearning doesn't become the term of choice.
