The Google TV—or rather, Google's software for set-top boxes—is one step closer to reality, according to sources speaking to the Wall Street Journal. Google is reportedly preparing to announce the software at next month's Google I/O conference, where developers may be able to get their feet wet writing applications for the platform, though the sources cautioned that Google might back off on the announcement if it's not quite ready by then.

Google's TV plans have yet to be officially confirmed, though they have been rumored for at least a month now. Consistent with the company's strategy in other areas, Google isn't expected to be involved in manufacturing set-top boxes; rather, the company is supposedly developing a version of Android that would be especially conducive to the big screen. Third-party developers would then be able to write their own apps for the devices, giving more openness and flexibility to people's TV watching habits.

According to the WSJ, hardware makers like Sony, Intel, and Logitech are interested in rolling out devices that work with Google's software. On top of that, Google is reportedly in the process of testing a sort of "television search" with the Dish Network, which allows users to search for content on the Internet and from Dish's programming.

We're still left a little unsure of how well the Google TV project will succeed, given the fact that there are already a handful of other set-top boxes available (and some of them for pretty cheap). However, if the UI is good and the developer community gets on board, there's potential for this device (or, more likely: devices) to fill a small gap in the market. After all, there are few set-top boxes right now that aren't full-blown HTPCs, but still give developers the freedom to develop their own apps, and their growing familiarity with Android—thanks to the mobile world—would certainly help.
