Action is already underway at the 2016 Summer Olympics in Rio de Janeiro, but the event doesn't formally commence until Friday's opening ceremony.
Although the ceremony begins at 7 p.m. ET, NBC Sports Group chairman Mark Lazarus confirmed to Philly.com's Jonathan Tannenwald that the network won't air the presentation until 8 p.m. ET. Fans who plan on live-streaming the opening ceremony can watch on the NBC Sports app.
So far, the Olympics haven't gotten off to a rousing start.
This isn't the first year infrastructure and security concerns were dominant storylines in the buildup to an Olympics.
