However, globalization has recently changed much of this calculus. Advances in technology have blurred the line between what can be considered foreign or domestic, and trade agreements have limited the options that governments may choose in giving preferential treatment to domestic goods. In 1993, this question of domestic versus foreign production surfaced when Time Warner, the world's largest communications company, started to produce a split-run version of one of its U.S. magazines, Sports Illustrated. Thanks to new technology, Time Warner was able to print a split-run Sports Illustrated Canada without it being stopped at the border. They produced the magazine in the United States and then transmitted the magazine’s content electronically to a Canadian printer via satellite.
