The other day, Google announced that they are adding more sources of data to Google Trends. So now instead of just web search data, Google will pull in data from News, Shopping, Images and YouTube. Google said they are "opening up more data to show what people in the world are looking for, as they're looking for it."
So now with your keyword research, you can use Google Trends to find even more valuable data. Google Trends lets you really slice and dice the information by source, location, type and many other ways. I highly recommend marketers take a look at it.
You can learn more about these new additions over here.
