Nokia has announced how the advertising on its content-sharing Mosh network will work, reports ClickZ.

Mosh will allow people to upload content to profiles that can be shared with friends via mobile devices. Content can be uploaded either directly from a mobile device, or through the web.

Banner advertising on mobile sites will, of course, be contextually relevant to the content they appear with. So if a group of movie fans is constantly uploading homemade reviews, the likelihood is high movie-related ads will populate that group.

Nokia will start off selling the ads in-house, but has not ruled out partnering with an ad network. These could include mobile firm Enpocket, which Nokia acquired just last month.
