WHY YES, THE U.S.-based global media may be at the cusp of a cultural turning point. Check out Fox's TV drama, "Touch," the first post-modern, cross-border, cross-cultural, cross-over-to-the-global-mainstream show on a major network. Launched last month in 100 markets worldwide, the visionary show is a new emerging model, a transnational and transmedia venture that could be the norm a decade from now. Short-term ratings trump all, so "Touch" -- years ahead of its time --may not last long. But the model will thrive in various incarnations.
