Swedish music-streaming company Spotify AB on Wednesday launched programmatic ad buying for all its markets, allowing advertisers to target its 70 million nonpaying users by age, gender, genres and playlists in real time […] such as listeners who are commuting, working out, dining, dating, partying or relaxing.
Nothing says “great date night” like an advertiser breaking into your playlist to sell you something.
