CTIA fueled some significant mobile news this week as Google, Nokia and Yahoo are about to crash helmets over the next mobile killer app.

Google has made a couple of significant steps this week. The more significant announcement came on Monday, as a strategic deal with LG was announced. Mike Evant reports that Google and LG will preinstall Google Maps, Gmail and Blogger on a wide variety of LG phones, making it a no brainer for carriers to ship and for users to try.

In addition, YouTube will be launching a mobile site as soon as the exclusivity period with Verizon Wireless expires. Unlike the Verizon version which is client based, the mobile YouTube will be WAP based. It will be interesting to see how YouTube deals with video streaming issues across different carriers, networks and devices. All in all a “two punch strategy”, Google for text and YouTube for video, could end up being very effective.

Nokia has not kept quiet. Unwired view is telling us about Nokia’s patent bound semantic visual search engine, screen shots and further explanation of the search process is provided. Katie Fehrenbacher speculates about the natural synergy with Nokia’s camera phones and if half the rumors are true, Google will soon have to go back to protecting home turf, at least when it comes to search innovation.

Yahoo has not kept silent and may very well be making the most concrete steps to date. The introduction of Mobile OneSearch is a promising mass market step, taking search to every internet enabled phone. Yahoo already offers Yahoo Go, the full blown Yahoo experience, to the high end, and together with OneSearch a comprehensive strategy seems to be forming. 

These seemingly little steps are very significant for a number of reasons. Such proactive steps by handset manufacturers and web titans take the carriers further out of the “next killer app” equation. In addition, these provide indication that search, rich content discovery and messaging are the areas where the leading players look for the next killer app. Search has never been carrier territory and carriers have struggled with putting together winning propositions around content. On the other hand carriers do make a lot of money from content and tons of money from messaging. The battle over who owns what asset is definitely not over, but this time, I believe, the space is mature enough to focus on the criteria for splitting the larger pie rather than fighting over who gets to burn it.
