If anyone needed more proof that TV on cellphones and other portable devices is here to stay, one need only take a look at old media stalwart Nielsen Media Research's latest move, who are set to expand their tracking to just about everything that can pick up an episode of SpongeBob Squarepants. Not the least of which, of course, is cellphones. Nielsen plans to track all these devices with something the company calls "Solo Meters," which are independent of any particular portable media device. In the case of cellphones and other devices with WiFi or Bluetooth capability, the tiny meter will passively listen to communications from the device. For other devices, Nielsen will use a small in-line meter that's attached between the device and the headphones -- how that works exactly, we're not sure.
