At the time of writing, 40,189 items have been published. Of these, 10,882 were added in the last 90 days and 4,770 were added in the last 30 days. These items come from 10,731 different publishers.

These numbers are from our own tracking system, which is also used to power the All About Windows Phone Apps & Games section, where you can browse all of the applications and games, and install them via links to Zune Desktop, the web based Marketplace, or install them directly by scanning the QR Code with Bing Vision on your smartphone.

At the current growth rate, we estimate that Windows Phone Marketplace will reach the 50,000 app mark in the second or third week of January 2012. However, it is possible that this mark may be reached before the end of the year if submission rates accelerate.

In common with other application stores, the total number of published items is not the same as the number of items available to consumers. Of the 40,198 items published to the Marketplace, just over 5,500 are no longer available (removed by Microsoft or withdrawn by the publisher). In addition, some apps are only available in select markets. This means the number of available items to a consumer, in a given market, is lower than the number of published items. The current approximate figures are: US (33,950), UK (32,332), France (31,672), Spain (30,482), Italy (30,346), Germany (30,260), Australia (30,2650), India (30,371) and Singapore (29,423).



During the last four weeks, an average of around 165 new content items have been added each day. This number is significantly higher than in the summer. The most likely explanation for the increased number of apps being added is a growing momentum behind the platform, and the release of Mango which roughly coincided with the start of the increase. The end of the quiet summer season and the announcement of the first Nokia devices may also be contributing factors.

Content by category

The chart below shows the proportion of content in each of the Windows Phone Marketplace's top level categories. As you might expect, games is the single biggest category (15%). The next three biggest categories are books + reference (15%), tools + productivity (14%) and entertainment (13%). This means the four biggest categories (out of 17) make up 57% of the content.
