Facebook will use a new audio fingerprinting tool to detect what movies, music, or TV shows you're watching or listening to.
The social network is doing away with clumsy hashtags and replacing them with an audio fingerprinting tool. This means that Facebook will be able to detect what TV shows, movies, or music their users are watching or listening to via the user's smartphone. When the feature is turned on, an audio icon will appear when a user posts a status. If Facebook can find a match for the song, the TV show, or the movie, the user can choose to add it to their status. Anyone who sees the status update can see or hear a 30-second preview of the media.
According to Facebook, the feature will launch "in the coming weeks" on iOS and Android. Wired's Ryan Tate pointed to the possibility of Facebook using the feature for monetization, allowing content producers to somehow take advantage of second-screen usage for advertisement.
