(Telecompaper) Spotify reported strong results for the fourth quarter, at the high end of its outlook thanks to a strong holiday sales campaign. As flagged in its previous quarterly report, the company expects some pressure on margins in 2019, as it launches a new strategy to grow revenue through offering podcasts and other audio content besides music. The group confirmed the acquisitions of Gimlet Media and Anchor to drive the podcast business and said more takeovers are planned this year.
