Use of GPS is becoming commoner every day. Already, there are tons of location based apps for modern mobile phones and many of them have become popular. Google recently launched a controversial one named Latitude.
While reading up about GPS and related stuff, i came across this interesting idea- using TV signals (instead of GPS signals) to locate position. The method of positioning is roughly the same but, the hardware required will certainly be different. A company called Rosum has created a product which uses TV signals to locate your position (if you are in America). According to them, TV signal based positioning has many advantages over traditional GPS. More about it here.
