Expo '70

Now that the Shanghai Expo is coming up, let's look back at the previously mentioned Osaka Expo 1970. That was a kind of exciting future represented there!

Shanghai expo 2010

Having visited both the 2000 Expo in Hanover and the 2005 Expo in Aichi, I really feel like going to Shanghai upon seeing these pictures of the half-finished pavilions for the 2010 Expo. Hope I can make it happen this year! One thing that's for sure is that the Shanghai Expo will be the biggest Expo ever, and therefore the biggest event ever held in human history. The projected visitor figure of 70 million will surpass the 64 million visitors of the 1970 Osaka Expo, so far the biggest ever. Also, it is unlikely that any other country (except maybe India) will ever host a bigger Expo.
