It's almost the end of 2008 ("good riddens" comes to my mind!) - and we've been exploring a bit. Steve Rubel had a great blog post this morning about using Google's Insights for Search feature to read the "tea leaves" about trends in 2009. He calls it "the closest thing we have to a global time capsule."
One interesting result I found was looking at how PayPal has trended over the last four years - with over twice as much interest demonstrated in PayPal today vs. four years ago.
Another interesting result in the PayPal summary is the strong interest in the UK vs. the US, France and other markets around the world. The top PayPal search term is "PayPal UK" - wonder why that is?
Here's one for Twitter - showing how interest in Twitter has grown like a weed during 2008.
Using the Google Insights for Search tool, you can search for and compare multiple terms - for example, here's PayPal vs. MasterCard - showing search interest in MasterCard remaining flat while PayPal's grew steadily. Curiously, if you look at the top searches related to MasterCard, the top result is "mastercard visa".
