A few posts ago, I linked to an article about micromarketing and the long tail. This link is a blog by the subject of that article and will soon become a book. The graph here shows the percentage of hit (gold, platinum and multi-platinum) records being sold as a percentage of all records being sold. That number is decreasing.

Chris Anderson, the author, proposes this trend will continue across all products that are marketed, with the result that people will buy fewer of the blockbuster products (like gold records or Tom Cruise movies) and buy more niche products.
