Other than Facebook Yahoo and Tumbler have added the same type feature to its network for TV and movies fans. But in these network commenting into a broader discussion about a particular show isn’t the smoothest of tasks.

Wednesday, on Blog post Facebook is rolling out its new audio fingerprinting tool. With audio fingerprinting, you needn't go looking for a hashtag . Instead, you click a button on your Facebook mobile app, it listens to the TV show you’re watching, and then it automatically links your comments to the right online forum.

If you’ve turned the feature on, you’ll see an audio icon moving on the screen when you write a status update. If the feature finds a match, you can then choose to add the song, TV show or movie to your post.Like with any post, you choose who can see it. You can also turn the feature off at any time by clicking the audio icon in the top right of the screen.The features is not available yet, but will be coming soon for the iOS and Android users.
