Verizon has promised to stop selling user location data to third parties in response to a privacy campaign by US Senator Ron Wyden (D-OR).

In a letter [PDF] to the lawmaker, the American telco giant said it has "conducted a comprehensive review" of its "location aggregator program" and as a result would kill the agreements it has with the two companies in the program, LocationSmart and Zumigo.
