Writing Background Content/Reviews of Key App Stores

We need some background information on the key app stores.

The work needs to be in English focusing on global/US centric app stores.

Examples of previous works will be required to secure the project.

For each app store listed, we are looking for up to 400 words on each covering the key information

1. App Store Name (e.g Amazon App Store)
2. Address e.g. http://www.amazon.com/mobile-apps/
3. Which platforms does this work for (e.g. Android Only, Desktop apps, mac, iPhone etc.)
4. How many apps are listed (and source if it is a third party figure)
5. Brief Description ( c. 150 words)
6. Any noticeable brand apps (e.g. Banks, Automotive Brands etc.) - we sill share a Distimo report for additional guides of brand examples

We need to review the following app stores:

Amazon App Store
Apple App Store (iTunes Apps)
Apple Mac Store (OSX Lion)
Blackberry App Worls
Google Android Market
Windows Phone 7 Marketplace
