In 2014, Twitter, the online messaging platform, was face to face with some difficult choices. Share value had halved in the past year and many believed that the social network had peaked at around 20 percent of the size of Facebook. Twitter has been trying to find ways to boost the amount of time that users spend on the platform. It was actively looking to acquire online music services and, according to many, had set its sights on both Sound- Cloud, valued at $700 million, and Spotify, valued at $4 billion. In acquiring new and successful businesses such as those that offer music streaming services, Twitter would not only be enjoying its largest acquisition to date, but would also be securing new areas for growth. Acquisitions are, however, not new for Twitter. It bought the start-up Vine, a video-clip sharing service, in 2012, and recently acquired Gnip, a provider of social data. The problem is that Twitter is not profitable and may not have large sums of cash to acquire a music service.
