Newsmap is a neat way to see what the top news stories are in many different countries. According to their blog, "In Newsmap, the size of each cell is determined by the amount of related articles that exist inside each news cluster that the Google News Aggregator presents. In that way users can quickly identify which news stories have been given the most coverage, viewing the map by region, topic or time. Through that process it still accentuates the importance of a given article."
This would be a great tool for social studies teachers to quickly show students what the top news stories are for that day. You can click from country to country to see how the news importance changes by location. Give it a try!
