Comprehensive guide to a flat rate model for music
Author, speaker and Media Futurist Gerd Leonard has a pretty comprehensive round-up of flat-rate models for music in preparation for his session at Midemnet 2009.
It includes Google in China, Orange, TDC, Nokia, Sony-Ericsson, T-Mobile, Netcom, STIM, and possibly Warner Music Group.
He also links back to his excellent post and presentation on The Future Revenues for Content Creators: Attention Revenues Up, Copy Revenues Down.
Both posts are essential reading!
