NBC's ?Jesus Christ Superstar Live? converted 9.360 million total viewers into believers last night, topping its Easter Sunday competition in the process. The live TV musical earned a high rating among adults 18 to 49 ? that demo number was also better than ABC?s ?American Idol? and anything else that aired in primetime on Easter evening. Those Nielsen numbers could and probably will adjust up in fast official numbers, which are expected a little later today.
