"Who Wants to Be a Millionaire" dipped sharply in ratings this week, making room for 18.9 million Americans who tuned in to "Frasier" to see Niles and Daphne together at last. The game show averaged 19 million viewers in October, a 21 percent drop from its average of 24 million from January through September, according to Nielsen Media Research. ABC attributes the plunge to the fact that "Millionaire," which is now on four nights a week, has had some stiff competition this month -- including baseball playoffs, The World Series, and premieres of competing network shows. Executive Producer Michael Davies says that in the end, he has no doubt that "Millionaire" will stay on top, even referring to the show as "the Energizer bunny," and adding that it is "going to keep on going when everybody else is in repeats."
