Audience measurement specialist Nielsen is buying media and entertainment metadata provider Gracenote from the Tribune Media Company for around $560 million (€539.5m).

Nielsen says the deal means it acquires the data and technology that underpins the programming guides and personalised user experience for major video, music, audio and sports content. The acquisition extends Nielsen’s footprint with major clients by including Gracenote’s global content database which spans across platforms including multichannel video programming distributors (MVPDs), smart televisions, streaming music services, connected devices, media players and in-car infotainment systems.
