Use of browser history file to determine web site reach

1. A method of metering a Web site, the method comprising:

loading a first monitoring application on a device to be monitored without modifying a browser on the device, wherein the monitoring application is separate from the browser;

retrieving, using the first monitoring application, a reference to a Web site from a history stored by the browser on the device, the history representative of Web sites accessed using the browser, the reference stored by the browser before the monitoring application is loaded, wherein the history stores the reference to the Web site in response to the browser accessing the Web site; and

providing the reference to a second application different from the first monitoring application.

2. A method as defined in claim 1 , wherein the second application is located on a collection server.

3. A method as defined in claim 1 , wherein providing the reference to the second application comprises storing the reference in a log on the device.

4. A method as defined in claim 1 , wherein the second application executes at a second device different than the device.

5. A method as defined in claim 1 , further comprising transmitting the first monitoring application to the device.

6. A method as defined in claim 5 , wherein the second application executes at a second device different than the device and the second device is further to execute the second application.

7. A method as defined in claim 1 , wherein the reference includes an identity associated with the device.

8. A method as defined in claim 1 , wherein the history has a first format and the first monitoring application is to operate with browser histories having the first format.

9. A tangible computer readable storage disc or storage device, the storage medium comprising a first monitoring application comprising instructions that, when executed, cause an electronic device to at least:

retrieve a reference to a Web site from a history stored by a browser on the electronic device, the history representative of Web sites accessed using the browser, the history to store the reference to the Web site in response to the browser accessing the Web site, the reference stored by the browser before the first monitoring application is loaded, the first monitoring application being separate from the browser; and

provide the reference to a second application different from the first monitoring application.

10. A computer readable storage disc or storage device as defined in claim 9 , wherein the second application is located on a collection server.

11. A computer readable storage disc or storage device as defined in claim 9 , wherein the instructions are to cause the electronic device to provide the reference to the second application by storing the reference in a log on the electronic device and subsequently transmitting the stored reference to the second application.

12. A computer readable storage disc or storage device as defined in claim 9 , wherein the second application is to execute at a second electronic device different than the electronic device.

13. A computer readable storage disc or storage device as defined in claim 9 , wherein the instructions are transmitted to the electronic device from the second electronic device.

14. A computer readable storage disc or storage device as defined in claim 13 , wherein the second application is to execute at a second electronic device different than the electronic device.

15. A computer readable storage disc or storage device as defined in claim 9 , wherein the reference includes an identity associated with the electronic device.

16. A computer readable storage disc or storage device as defined in claim 9 , wherein the history has a first format and the first monitoring application is to operate with browser histories having the first format.

17. A method of metering a Web site comprising:

receiving a message from a first computer at a second computer after a browser history at the first computer is populated with information, wherein the message includes an identity indication of the first computer and the browser history is maintained by browser functionality native to the browser; and

sending an application to the first computer from the second computer in response to the message, wherein, when the application is executed at the first computer, the application accesses the browser history, extracts a portion of the browser history, and inserts the extracted portion of the browser history into a communication directed to a third computer.

18. A method as defined in claim 17 , wherein the identity indication references an identity of a panelist.

19. A method as defined in claim 17 , wherein the identity indication includes a user name.

20. A method as defined in claim 17 , wherein the second computer is the third computer.

21. A method as defined in claim 17 , further comprising storing in the third computer the portion of the browser history and storing in the third computer browser history information from other computers.

22. A method as defined in claim 17 , wherein the message includes credentials to log onto a web page hosted by the second computer.

23. A method as defined in claim 17 , wherein the browser history has a first format and the application is to operate with browser histories having the first format.

24. A method as defined in claim 17 , further comprising sending a communication to the first computer, the communication including a request to send the message to the second computer.

25. A method as defined in claim 17 , wherein the communication includes a webpage.
