- Global PMP/MP3 player shipments will go up to 268.6 million units in 2011 at a Compound Annual Growth Rate (CAGR) of 13% from 128.7 million units in 2005

- In 2007, PMP shipments are expected to rise to 216.9 million units, up 21.8% from 178.1 million in 2006.

Broadband paid video market will grow from $300 million last year to a whopping $4.5 billion in 2010. Music will have a more meagre growth from $1.6 billion to $5 billion at that same time frame
