With less than 50 days before the opening ceremony of the 2024 Summer Olympics, NBC has finalized its live preliminary and finals broadcasting crews for three of the main events on the program: swimming, gymnastics and track and field.

The wrinkle for the Paris Games is that there will be two top announcing teams for these sports. For swimming and track and field, one team will call live preliminary heats and a different team will handle the live finals in the afternoon as well as the primetime show. For gymnastics, one announcing team has the live daytime coverage and another will be featured in the primetime window. All coverage will be streamed live on Peacock.

The beauty of the European time zone and broadcasting in the United States, said NBC Olympics president and executive producer Molly Solomon, is that NBC will be live in some capacity from 4 a.m. ET until 6 p.m. ET every competition day.

"We are putting everything on live all day long," Solomon told USA TODAY Sports. "Is it on NBC, is it on one of our NBCUniversal cable networks? And everything is going to be live on Peacock. Really, the consumer can find whatever they’re looking for live during the day."

Here are the NBC broadcast teams for swimming, gymnastics and track and field:
