An earlier post referenced the rumor that Google was potentially entering the wireless market. The original story on Business 2.0 speculated that if Google could track the geographical location of a wireless user, they could target advertising more precisely.
Whether that’s true or not is still a matter of speculation. What is true is that this rumor has legs. Seven days after the fact the IT related web news sources are still reporting on it. What probably produced the original rumor is this page on Google’s web site. It is instructions to users in a test market in San Francisco. Is this intended for a broader audience? I don’t know – but it is fun (evidently) to speculate.
