Media: Closure of Greek public service broadcaster; Apple's iTunes Radio; the BBC's lost £100m

Summary: We hear from Greece about the sudden closure of the public service broadcaster, ERT, which was taken off air last night; we look at Apple's new iTunes Radio and claims that it will challenge commercial radio in the UK; and Margaret Hodge MP, chair of the Public Accounts Committee, is looking into the BBC's loss of £100m over a technology project - she explains why she wants the BBC's former DG Mark Thompson to return to the UK to answer questions.
