Olympics history will be made tonight — when Meredith Vieira becomes the first woman to ever anchor NBC’s prime time Olympic coverage. Vieira is taking over for Matt Lauer, who has filled in for the last three days as Bob Costas continues to deal with the effects of an infection that began in his left eye and spread to his right eye earlier this week.That was TV-historic too, ending Costas’ streak of 157 consecutive appearances as NBC’s Olympics anchor in primetime. It was the first time since 1988 Costas did not host the coverage. He’d soldiered on with the infection in one eye — then two — the first few days of NBC’s Olympics coverage before calling Costas in from the “bullpen” on Tuesday.”
