Apologies for the long quote below, but it introduces this topic far more succinctly than I can. the operant term here is Creepy!
“As far as corporate notices go, they don’t get much creepier than this recent alert from Verizon Wireless.
The company says it’s “enhancing” its Relevant Mobile Advertising program, which it uses to collect data on customers’ online habits so that marketers can pitch stuff at them with greater precision.
“In addition to the customer information that’s currently part of the program, we will soon use an anonymous, unique identifier we create when you register on our websites,” Verizon Wireless is telling customers.
“This identifier may allow an advertiser to use information they have about your visits to websites from your desktop computer to deliver marketing messages to mobile devices on our network,” it says.
That means exactly what it looks like: Verizon will monitor not just your wireless activities but also what you do on your wired or Wi-Fi-connected laptop or desktop computer — even if your computer doesn’t have a Verizon connection.”
