Method and system for message modification and content selection

A system comprising:

• a processor;
• and
• a memory containing instructions that, when executed, cause the processor to:
• intercept a first message during transmission from a sending party to a receiving party;
• upon a determination that the receiving party is registered with a messaging service, identify at least a first data channel and a second data channel based on interests of the receiving party, wherein the first data channel includes at least a first data item and a second data item, and the second channel includes at least a third data item and a fourth data item;
• select the first data channel according to a channel selection rule that dictates selection of either the first data channel or the second data channel based at least on a previous channel selected upon intercepting a previous message during transmission to the receiving party;
• select the first data item according to a data item selection rule that dictates selection of either the first data item or the second data item based at least on a determined proximity between a transmission time of the first message and a transmission time of the first data item;
• and
• append content retrieved from the first data item to the first message.

A non-transitory computer-readable medium containing instructions that, when executed by a computing device, cause the computing device to:

• intercept a first message during transmission from a sending party to a receiving party;
• upon a determination that the receiving party is registered with a messaging service, identify at least a first data channel and a second data channel based on interests of the receiving party, wherein the first data channel includes at least a first data item and a second data item, and the second channel includes at least a third data item and a fourth data item;
• select the first data channel according to a channel selection rule that dictates selection of either the first data channel or the second data channel based at least on a previous channel selected upon intercepting a previous message during transmission to the receiving party;
• select the first data item according to a data item selection rule that dictates selection of either the first data item or the second data item based at least on a determined proximity between a transmission time of the first message and a transmission time of the first data item;
• and
• append content retrieved from the first data item to the first message.
