The document discusses how businesses can market new ideas to maintain growth and improve productivity. It describes the hub and spoke model, where the main website is the central "hub" that drives visitors and provides company information. Social media and other online presences represent "spokes" that support the hub by spreading its message and building an audience. Using this model allows businesses to effectively market new ideas to potential customers in a cost-efficient manner by reaching more people through existing channels or new audiences with different messages.
