System for efficient transmission of json objects from a server to multiple portable computing devices

A networked system comprising:

• (a) a server comprising:
• a processor,
• a non-transitory memory storing JSON (JavaScript Object Notation) objects, and
• a network adapter controlled by said processor and configured to transmit the JSON objects over a WAN (Wide Area Network);
• and
• (b) multiple portable computing devices, each comprising:
• a display,
• a processor,
• a network adapter controlled by said processor and configured to receive at least one of the JSON objects from said server over the WAN, and
• a non-transitory memory storing instructions that, when executed by said processor:
• parse each of the JSON objects into HTML (HyperText Markup Language), and
• render the HTML for presentation on said display, wherein the presentation is inside a designated space in a software application running on said portable computing device simultaneously with receipt of the respective one of said JSON objects.
