PBS acknowledged that its live "A Capitol Fourth" broadcast of this year's Washington, D.C., fireworks show was spliced in with video from previous years' spectacles, NBC News reported.
Hundreds of viewers complained on the annual show's Twitter and Facebook pages that the fireworks display couldn't be live because the images were in clear weather, a stark contrast to the actual heavily overcast and foggy Monday night.
The show's Facebook and Twitter pages acknowledged that the show was " a combination of the best fireworks from this year and previous years."
PBS didn't immediately return NBC News' calls for comment Monday night.
