DISCLAIMER OF WARRANTIES AND LIABILITY
We work hard to make the Discovery Sites interesting and enjoyable places, but we cannot guarantee that our users will always find everything to their liking. Please read this Disclaimer carefully before using any of the Discovery Sites.
YOU AGREE THAT YOUR USE OF THE DISCOVERY SITES IS AT YOUR SOLE RISK. BECAUSE OF THE NUMBER OF POSSIBLE SOURCES OF INFORMATION AVAILABLE THROUGH THE DISCOVERY SITES, AND THE INHERENT HAZARDS AND UNCERTAINTIES OF ELECTRONIC DISTRIBUTION, THERE MAY BE DELAYS, OMISSIONS, INACCURACIES OR OTHER PROBLEMS WITH SUCH INFORMATION.

THE DISCOVERY SITES ARE PROVIDED TO YOU AS IS, WITH ALL FAULTS, AND AS AVAILABLE. THE DISCOVERY SITES, DISCOVERY COMMUNICATIONS, LLC AND THEIR AFFILIATES, AGENTS AND LICENSORS CANNOT AND DO NOT WARRANT THE ACCURACY, COMPLETENESS, CURRENTNESS, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF THE INFORMATION AVAILABLE THROUGH THE DISCOVERY SITES, NOR DO THEY GUARANTEE THAT THE DISCOVERY SITES WILL BE ERROR-FREE OR CONTINUOUSLY AVAILABLE, OR THAT THE DISCOVERY SITES WILL BE FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS.

The Discovery staff works hard to ensure that information we post to the Discovery Sites is both timely and accurate. But the news changes over time and reports that were accurate when posted may quickly become old news. Though we may post follow-up reports, and may continue to provide access to the original report, as in an archive of news stories, for example, we don't go back and change the original report to reflect new developments. If you're looking for the most recent information on a given subject, and not the history of how the story unfolded, be sure you're not looking at an out-of-date report.
You agree to indemnify, defend and hold harmless Discovery Communications, LLC, its affiliates, and their officers, directors, employees, agents, licensors and suppliers, from and against any and all losses, expenses, damages and costs (including reasonable attorneys' fees) resulting from any violation of this Visitor Agreement or any activity related to your account (including negligent or wrongful conduct) by you or any other person accessing any Discovery Site using your account.
This Visitor Agreement has been made in and shall be construed in accordance with the laws of the State of Maryland. By using the Discovery Sites, you consent to the exclusive jurisdiction of the state and federal courts located in Maryland, in all disputes arising out of or relating to this Visitor Agreement.
In the event that any portion of this Visitor Agreement is found to be invalid or unenforceable for any reason, such invalidity or unenforceability shall not affect the enforceability or validity of any other portion of this Visitor Agreement, which shall remain in full force and effect and be construed as if the invalid or unenforceable portion were not part of the Visitor Agreement.
