Through what channel did e-commerce first evolve?

The correct choice reflects the initial pathway through which e-commerce began to take shape. E-commerce first evolved significantly through online advertising sales, as businesses recognized the potential of the internet as a marketplace and advertising channel. This approach allowed companies to reach consumers directly, promoting products and services through various online platforms.

During the early stages of the internet, companies began experimenting with different ways to leverage this emerging technology for commercial purposes. Online advertising became a primary method for generating revenue, as it enabled businesses to connect with a larger audience without the geographical limitations of traditional advertising.

While other options like internet portals, online book sales, and internet service providers played important roles in the evolution of the internet and its commercial applications, the rise of online advertising sales marked the beginning of e-commerce as it introduced the idea of engaging customers directly through the web, paving the way for more complex online sales models in the future.
