Popular Music tagging app Shazam has announced that the app's upgraded functionality will let users tag any TV show on any channel in order to know more about the music as well as the actors featured. The announcement has been made after it was revealed that the company has now reached the 250 million users milestone.

Shazam users can now use the app as a "TV companion app" with any TV show to access cast details and photos, music in the show, celebrity gossip, trivia, celebrity tweets, and links to additional information (via Wikipedia, IMDB and the official site for the show). Moreover, the ability to instantly share and comment on the show or episode on social platforms - Facebook and Twitter also exists.

"With more than a quarter of a billion people who have used Shazam worldwide, no other app has our scale when it comes to offering the opportunity to engage with the media that interests them the most, whether it's music or television. And now, that experience is even better than before, enabling people in the US to engage with any show at any time," said Andrew Fisher, Shazam CEO.

Apart from Shazam's TV expansion, the app has also enhanced social features for Android and iOS users. When users activate the Shazam Friends feature in the app, they can see what their Facebook friends are tagging and will be able to make comments about their friends' tags directly from the app.

Moreover, after activation, people's tags will appear on their Facebook profile in their timeline, enabling users to discuss what they are watching or listening to with their friends on Facebook. Users can also change the Facebook sharing preferences in the Settings section of the app. Social sharing via Twitter and Google+ are also available.

The new sharing features will arrive in the coming weeks with additional features to be added in the coming months, which includes being able to Like tags.
