I’ve gone into NBC’s Olympics channel and found some of the 2022 Winter Olympics, but I’m having trouble finding anything from the 2020 Summer Olympics, which actually took place in '21. In particular, I’m looking for handball. I’d like to watch it on my Roku device. I could care less if it’s the NBC coverage or something else.
You can find a lot of Olympics stuff on YouTube, you just have to search for specific years and events.
There might be footage at the IOC website, olympics.org.
