Google Planning Mobile Media Search Engine?

Google is planning to launch a mobile media search engine to help consumers find and buy ringtones, games and other mobile content, according to a Wall Street Journal report (subscription required).

According to the WSJ, "people familiar with the matter" say that the system will allow users to find and pay for mobile content, and that Google will eventually monetize the search with AdWords. Google has reportedly been working with mobile content providers to index their content for several months, but technical issues have delayed its launch.

The service will also potentially include a social networking element, allowing Gmail users to exchange content.
