I love to talk shit on huge broadcasters but using their app for the olympics has been amazing. I just watched 2 days of replays from their app, all with minimal or no commentary, and all with few commercials (like 1/30 minutes).

Not only do you get replays for literally every event, but they don't even spoil them with the final scores or results.

Edit: It looks like I failed to mention that cable is required so that's a huge caveat. Also some folks seem to get more commercials than I have.
