Round four of the Friends/Survivor face-off got underway last night, and not surprisingly, America was there for NBC's Emmy-winning sitcom. According to Nielsen, the ninth (and supposedly final) season premiere of Friends attracted a staggering 33.3 million viewers and easily beat the debut of Survivor: Thailand (21.4 million viewers). At 9 pm, CBS took control with the return of CSI averaging a series-high 30 million viewers. The Eye network's 10 pm debut of Without A Trace also fared well with 16.6 million viewers the most competitive drama finish opposite an ER premiere in eight years, reports Variety's numbers cruncher Rick Kissell. Of course, with 26.7 million viewers, ER was hardly on life support.
