Sometimes it seems things change quickly online, sometimes not so quickly.<p>It’s been about 20 years since we built “broadband activated merchandising” (aka “BAM”) for selling wrestling hats and t-shirts at scale to millions of viewers, contextually triggered along side WWE live event video streams:<p><i>A system and method for enhancing electronic commerce and/or communicating information concerning products and/or services in connection with multimedia (e.g., video) transmission and delivery is provided. The system and method facilitate targeted marketing and/or merchandising in connection with video streams delivered to users across a computer network, e.g., the Internet and/or the World Wide Web, by synchronizing ancillary content with the video stream. The method/system may be used in a broad range of applications for live, taped live and on-demand video streams.</i><p><a href="https://patents.google.com/patent/US20020019978A1/en" rel="nofollow">https://patents.google.com/patent/US20020019978A1/en</a><p>In your 640 or 800 px wide browser window, beside the live stream (320x240 at 700 kbps, ahem!), you had a product pane showing contextual offers you could add to your cart, and then check out when the event was over.<p>The stream metadata was fed by a producer watching the live action and using a e-commerce store event dashboard to choose what products to promote when.<p>For comparison, from this AWS article:<p><i>The team have added the ability to send timed metadata along with the video so that you can fire events in your application at crucial points in the live stream... you can build experiences that create a more valuable relationship with your viewers on your own websites and applications. For example, if you were live-streaming a product launch, you could synchronize additional product information to be displayed as new products appear in the video. You could even show a buy now button that allows viewers to purchase the exact product they are watching at that moment on the live-stream.</i><p>Pretty cool to see this descendant!
