Description of policies and practices relating to behavioral advertising and customer privacy

We provide our customers with information – and choices – about how their data might be used. We publicly post privacy policies and give customers the ability to opt-in to some programs and say no to others.

AT&T’s Privacy Center website informs customers about AT&T’s data practices, including: the types of information collected; how information is collected, used and shared within AT&T and with third parties; how it is secured; and how long it is kept.

To help customers understand our practices, we describe our technology and services in simple terms and provide a consolidated resource for privacy policies and rights such as those under the General Data Protection Regulation in Europe and the California Consumer Privacy Act.

Our advertising unit, Xandr, optimizes media spend across TV and digital properties for buyers and sellers. As part of our efforts to boost transparency, we offer an Online Advertising & Ad Tech Glossary to educate consumers on the advertising industry’s many technical terms. We ensure the data Xandr collects does not reflect names, email addresses or other information that directly identifies a user. And Xandr never sells data from our platform pertaining to any individual that we know is a minor.

Description of approach to identifying and addressing data security risks, including use of third-party cybersecurity standards

AT&T has developed and maintains the AT&T Security Policy and Requirements (ASPR), a set of security control standards based in part on leading industry standards such as ISO/IEC 27001:2013. ASPR aligns to laws and standards such as the National Institute of Standards and Technology (NIST) Cybersecurity Framework and NIST 800-53 as well as the European Union’s General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA) and Criminal Justice Information Services (CJIS).

AT&T also performs annual third-party certifications/audits – such as those for the payment card industry, Sarbanes-Oxley Act (SOX) and SSAE 18/ISAE 3402 (SOC) – to demonstrate compliance to our customers and our stakeholders.

AT&T maintains global ISO 27001 certification, which includes the information security management systems (ISMS) for the AT&T global IP network and customer-facing services.

Description of systems to provide unimpeded service during service interruptions

At AT&T, we design our network and operations to be resilient – so we’re prepared to provide essential communications and data connectivity for our customers and communities. Our global team of certified and experienced business continuity experts, led by our President of AT&T Network Engineering and Operations, works to maintain operations of key business processes by utilizing documented business continuity strategies, plans and procedures that are updated and exercised on an annual basis. Regular reports on our business continuity efforts are shared with the Audit Committee of the AT&T Board of Directors.

Our Business Continuity Management Program is certified to the international business continuity standard ISO 22301:2012. It’s also aligned with the Disaster Recovery Institute International Professional Practices, Business Continuity Institute Good Practice Guidelines, U.S. Department of Homeland Security National Incident Management System and ISO 31000.

Alignment with such standards demonstrates that AT&T is equipped to maintain business operations and serve our customers in the vital hours, days or weeks after disaster strikes.

To help ensure the resilience of the AT&T network, our systems collect billions of service-assurance measurements across our wired and wireless infrastructure every hour, informing us of events such as unforeseen outages or spiking bandwidth demands. We analyze this data in near real time, 24/7, to help optimize performance. If disruption occurs, network technicians – and, if needed, our Network Disaster Recovery personnel and fleet – are deployed to rapidly restore communications to affected areas.

Description of policies and procedures to ensuring pluralism in news media content

The AT&T Human Rights Policy states, “The role of a free press is fundamental to ensuring the security of human rights. At AT&T we consider the commitment to a free press to be a core value that is central to our mission. We will safeguard editorial independence and we will support efforts to ensure and advance freedom of expression across our platforms around the world.”

Our news organization, CNN, is committed to diversity across all screens and behind the scenes, and we actively invest in diversity recruiting and development programs. As demonstrated by our varied team of anchors, correspondents, producers, editors, contributors and guests around the globe, we know that to report the facts and uncover the truth, diverse perspectives are essential.

At CNN, we do not appeal to a specific point of view or political constituency. To the contrary, our reporters, producers, editors and writers aim for comprehensive journalism, which is enriched by the diversity of our employees. In our news coverage, we strive to present the whole story fairly and completely, so that readers and viewers may come to their own conclusions. And in our presentation of opinion and analysis, we strive to represent a range of viewpoints.

Our CNN website clearly identifies CNN’s parent company, WarnerMedia, a subsidiary of AT&T. And when CNN covers stories addressing AT&T, WarnerMedia or sister brands, we clearly disclose such relationships.

For more information, see our Media Pluralism, Ethics & Journalistic Integrity issue brief.


Total amount of monetary losses as a result of legal proceedings associated with libel or slander

AT&T is not able to provide this data, as it is proprietary and confidential.


Revenue from embedded advertising

AT&T is not able to provide this data, as it is proprietary and confidential.

Periodically, third-party branded products and/or services may appear or be referenced in WarnerMedia productions. In some cases, they are added by the content creators as organic set elements, relative to the environment or storyline; this brand inclusion generally does not involve compensation or consideration from the brand.

In other instances, either the content creator or WarnerMedia may enter a brand partnership with an advertiser to incorporate a product and/or service within a relevant storyline. In certain instances, these brand placements may be part of a larger media purchase. When done thoughtfully, inclusion of brands in content can benefit many parties:

  • The media/content creator – as a revenue source and a mechanism for reducing the overall cost of production
  • The audience – by enhancing content and offering advertising that is relevant and less intrusive
  • The advertiser – by developing an environment for their ad that drives deeper awareness and engagement with their product and/or service


Description of approach for ensuring journalistic integrity of news programming related to:

Truthfulness, accuracy, objectivity, fairness and accountability

Independence of content and/or transparency of potential bias

Protection of privacy and limitation of harm

Our commitment to responsible, fair and accurate journalism guides our news businessAt CNN, we practice and defend the highest principles of journalistic integrity and ethical standards. In our news coverage, our journalists present the story fairly and completely, so readers and viewers can make informed decisions. This commitment reflects one of AT&T’s core company values – to Embrace Freedom – which we apply to press, speech and beliefs.

Our reporters, producers, writers and editors work to confirm the facts before publishing articles on CNN digital or airing stories on CNN television. At CNN, fairness, integrity, diversity and accuracy are of the utmost importance to the brand, and systems are in place to maintain them. For example, news reports are reviewed by producers and copy editors – and particularly sensitive and investigative stories are reviewed further by a team of senior editors, standards and practices specialists, and media attorneys before they are broadcast or published.

Responsible and ethical journalism means that the CNN editorial staff maintains full editorial decision making for any segments or programs that are sponsored by our advertisers. And our journalists report on and hold to account our advertisers, other business partners and our parent company as they would any other company.

CNN conducts extensive and ongoing training to ensure employees connected to news gathering and reporting are fully aware of the scope and complexity of privacy law and the associated obligations toward confidentiality of news sources. Each news topic or situation involves unique circumstances that are addressed individually in connection with our legal and ethics teams.

We create, own and distribute intellectual property, including material protected by copyrights, registered or unregistered trademarks, trade names, patents, trade secrets or other proprietary rights (“Intellectual Property”). To protect this Intellectual Property, we rely on a combination of laws, license agreements, robust registration and enforcement, and the responsible actions of our employees.
