How can you delete your viewing history on Netflix?

To delete viewing history on Netflix, one needs to log in to their Netflix account on a web browser and navigate to the "Account" section. Under the profile for which they want to alter the viewing history, they will find the "Viewing activity" option. By clicking this, they'll be presented with a list of all the shows and movies they've watched. Next to each title, there's an icon that looks like a circle with a diagonal line through it. Clicking on this icon will remove the associated item from the viewing history. It might take up to 24 hours for the changes to reflect across all devices. Note that removing series from the history will require deleting episodes individually, and for convenience, there is an option to hide the entire series at once by selecting "Hide series?" after deleting a single episode.
