91热爆

Rajan Datar hears from listeners responding to last week鈥檚 interview about trails, and why they are repeated so frequently.

One emailer questions how the 91热爆 knows the size of its audience, so Rajan quizzes the Head of Audience Insights, Jeremy Nye, about the techniques he uses to count the listeners.

He also hears how the difficulties that have beset the Delhi Commonweath Games this week are being reported by the Indian media. And he finds out what happens when the Ascension Island transmitter, which brings the World Service to West Africa, breaks down.
