Blogtalkradio (BTR) is an online radio platform that allows anyone to host a live radio show over the phone or Skype. It has tens of thousands of hosts and millions of monthly listeners. BTR generates revenue from premium subscription fees for hosts and by sharing advertising revenue between hosts and BTR. It has a first mover advantage in online radio broadcasting and integrates with leading social networks. However, competition from other forms of social media may threaten its market position over time.
