NEW YORK — NBC acknowledged some critics Saturday in announcing it changed plans and will stream today’s Olympic closing ceremony live online.

The ceremony from London will still air on a tape-delayed basis on NBC in prime time. For the opening ceremony, NBC took some heat for not making the event available to anyone in the United States for hours after the fact.

The opening ceremony was watched by 40.7 million people, a bigger audience than for the Grammys and Oscars this year.

NBC has since found that streaming live all of the Olympic sports events online has not cut into its prime-time audience, which has been unexpectedly bigger than the 2008 Beijing Games.

“Going into the opening ceremony, we didn’t have a sense for what our ratings would be and what streaming would or wouldn’t do to our broadcasts,” said NBC Sports Chairman Mark Lazarus. “But we think we’ve learned enough and have promised to innovate and continually evolve our broadcast coverage.”

The stream is available to cable and satellite customers who go to NBCOlympics.com.
