It's a split between the advancements in communication and transportation.
It used to take months to get a message sent from London to New York, now it takes milliseconds. There didn't used to be a good way to get a message to a large mass of people spread out, but now even trivial things are broadcast to entire countries.
Transportation however, has affected trade like noone has ever imagined. People used to see foriegn goods as "exotic". People only brought back the good stuff since it cost so much to bring it back. Well, that "made in China" label isn't only on dishes and silk anymore. It's on that $2 mouse at office depot. Got a package you want sent to Zimbabwe? Sure, it'll take a few weeks still. ...unless you get it expidited, then it's only a couple of days (customs takes time). What about large items? Considering that supertankers can now hold half a million TONS of oil, big items are no longer a big issue. Even large structures (oil rigs) get shipped. But what if that cargo is yourself? Well, you can get to most every major city within 24 hours of deciding to go there. But how is your daily life affected? People used to be born, live, work, and die within 10 miles. We got cars now though, I commute 25 miles and it's not a big deal. Want to take a trip 400 miles away? Pack the overnight bags, you're going to be away for the weekend.
