Much ink has been spilled about the changes wrought with the coming of the internet. Much smarter people have given much better insight about these dramatic shifts. But let me throw my proverbial hat in the ring.
When you turn on the television you can see sights from around the world. Dig through imaginations on Sci-Fi channel or head to the markets of India on the Travel Channel. You can rent dvds about anything. But it is only on the internet where you can get the latest update on the developments of the People's Liberation Army Navy (China's Navy). Like any old intelligence analyst you can break down the meaning of new mast on a new ship, discuss capabilities, and give your opinion on how the USA should respond. Really amazing.
