Through this partnership, T-Mobile is hoping to increase the data usage regarding web navigation on its mobiles. This means that, from now on, T-Mobile will be using Yahoo!'s oneSearch, and its web services will be now known as Web2G. In addition, Yahoo! will be bringing in the sponsored search results, or will, in some cases, display advertising incorporated in the search results. The profits coming from these advertising results will be shared between the two companies, but the percentage that will go to each is currently unknown.

The leading company on the search and advertising markets is, as you all know, Google, and it is now starting to get ahead of the competition on the mobile segment as well. For example, a couple of months ago, Google and T-Mobile released the G1, running on the Android OS and also using several Google applications, such as Gmail, Google search or Google maps.

All the major companies are doing their best to attain some kind of a monopoly in different areas. For instance, Microsoft is said to be about to close a deal with Verizon Wireless, bringing in a guaranteed profit of $550 to $650 million per year. Yahoo!, on the other hand, has already expanded over to T-Mobile and O2, thus controlling now over 25% of the market share in Northern and Central Europe, and over 30% in the UK.

This competition is turning into a genuine war between the major companies mentioned earlier, each one trying to release a service or an application before the others, while also trying to get their technologies to as many distributors as possible. Examples are pretty relevant in these cases, such as that of Google releasing its Voice Search application for the iPhone, whereas Yahoo!, currently based onYahoo! oneSearch, has now also brought its own Voice Search to users, and is promising more to come.

As mobiles with advanced web browsing capabilities, like the iPhone or the BlackBerry, are more and more appreciated, all these applications and services will soon not be enough for the increasing number of new users, especially since they will learn to use them to the maximum, and will then ask for more. So, even if many believed lately that that users cannot keep up with all the applications released so frequently, shortly, the demand for improved such services is to become overwhelming if not for this fierce competition.
