Patent No. US8566164 (titled "Targeted online advertisements based on viewing or interacting with television advertisements") on Dec 31, 2007. The application was issued on Oct 22, 2013.
’164 is related to the field of targeted digital advertising and cross-platform user tracking. Specifically, it addresses the technical challenge of linking a user’s television viewing habits with their internet browsing activity to deliver synchronized marketing content. In modern home networks, devices often use dynamic addresses or operate behind different service provider infrastructures, making it difficult for advertisers to know that a person browsing on a laptop is the same person who just viewed a specific commercial on their television.
The underlying idea behind ’164 is to bridge the gap between the television set-top box and online devices by identifying when they share a common local area network connection. By recognizing that these two distinct pieces of hardware are communicating through the same gateway or modem, the system can link a set-top box identifier to an online access identifier. This allows the system to build a unified behavioral profile that spans both media without necessarily relying on the collection of sensitive personal data.
The claims of ’164 focus on a computer-implemented method and system that automatically directs targeted online advertisements to a user interface device based on prior television viewing behavior. The core mechanism involves associating a set-top box identifier with an online access identifier by detecting that both devices are connected independently to the same local network. This association is then used to retrieve a user profile containing data collected from television advertisement interactions to inform the selection of subsequent online ads.
In practice, the invention works by monitoring how a viewer interacts with commercials—such as whether they watched the full ad, muted it, or engaged with interactive prompts. When that same user later accesses the internet from a computer or smartphone on the same home network, the system recognizes the associated online access identifier. It then serves a follow-up digital ad that is contextually relevant to the television content previously consumed, creating a continuous brand experience across different screens.
This approach differentiates itself from prior solutions by eliminating the strict requirement for personally identifiable information (PII) to perform cross-device matching. Instead of needing a user's name or email to link accounts, the invention leverages the technical architecture of the home network itself. By using the shared network gateway as the link, the system can maintain targeting accuracy even as dynamic IP addresses change, ensuring that the relationship between the set-top box and the online device remains intact for the advertiser.
In the late 2000s when ’164 was filed, the delivery of digital media was characterized by a technical bifurcation between television broadcast infrastructures and packet-switched internet networks. At a time when television advertising was typically implemented using one-way linear broadcasts or closed-circuit Video-on-Demand systems, cross-platform data synchronization was hindered by the fact that systems commonly relied on independent hardware silos—specifically set-top boxes for video and personal computers for web access—rather than unified multi-screen ecosystems. Furthermore, hardware and software constraints made the correlation of user activity across these silos non-trivial, as network providers frequently utilized dynamic addressing protocols like DHCP, which caused device identifiers to change periodically and prevented persistent tracking without the use of static personally identifiable information.
The disclosed invention represents a meaningful technical advancement by establishing a cross-media architectural link that enables targeted online ad delivery or behavioral tracking based on specific television interactions. The solution utilizes a structural association between a set-top box identifier and an online access identifier, allowing the system to bridge the gap between television viewing data and online user interface devices even when those devices operate on dynamic IP addresses. By integrating automatically collected data from television advertisement interactions into a user profile that is electronically mapped to online access credentials, the architecture overcomes the technical constraint of device isolation. This enables the technical effect of synchronized cross-platform behavioral targeting and performance tracking without necessitating the continuous use of personally identifiable information to maintain the link between disparate hardware endpoints.
This patent contains 29 claims, with claims 1, 16, and 23 serving as the independent claims. The independent claims focus on a method, system, and computer-readable medium for delivering targeted online advertisements by associating an online user interface device with a television set-top box based on their shared connection to a common local area network, utilizing television viewing behavior to select online content without using personally identifiable information. The dependent claims generally serve to specify technical implementations such as the use of IP addresses, cookies, or tags for identification, the recording of associations in databases, the inclusion of specific user interaction data, and the protection of user privacy by preventing the transmission of behavioral profiles to television service providers.
