Web Beacons

NYSE employs a software technology that serves as a web tracking device to collect certain information about traffic to the NYSE web sites. This device is classified as a "web beacon" by the Network Advertising Initiative, which means that the scope of its collection is restricted to web site traffic data. It is similar in function to cookies. The main difference between cookies and web beacons is that web beacons are invisible on the page and are much smaller, about the size of the period at the end of this sentence. A P3P-compliant JavaScript cookie is set and collected by the tracking device to allow for differentiation between visitors to the sites. This data is used for tracking and reporting aggregate usage patterns on the web sites but does not include any personally identifiable information about individual visitors.
