Live Commercial Blocker

Automatically block TV commercials on live sports streams and play media of your choice in their place.

Live Commercial Blocker is a browser extension that works with virtually any live TV or sports streaming service, even the bootleg ones.

Think of it as an ad blocker for live TV, but instead of just muting or hiding commercials, it replaces them with content you actually want to watch or listen to while you wait for the game to return.
