Audible UK revenue soars 45% | The Bookseller

The growth of the audio market, which now represents 5% of the total trade market for books in the UK according to Nielsen, is "in no small part thanks to Audible", Enders' analysis said, because the company has opened up the market to people who don't usually buy books, such as young men.

However, it also dubbed Audible a "frenemy" for simultaneously "breathing new life" into the market and "putting publishers under pressure". It described its approach to bidding for audio rights and its investment in high-end productions as "aggressive", making it a player "more directly threatening to publishers in audio than Amazon publishing is in written books".
