Esta estrategia de marketing fue tan exitosa que en 1895 Coca-Cola era conocida en todos los estados de América y se convirtió en una de las marcas más reconocidas de la historia. Todo comenzó con un cupón y una gran bebida, por supuesto.
In 2008 the state of New York passed a law asserting sales tax jurisdiction over Amazon.com sales to New York residents. New York was aware of Amazon affiliates operating within the state. In Quill Corp. v. North Dakota, the US Supreme Court ruled that the presence of independent sales representatives may allow a state to require sales tax collections. New York determined that affiliates are such independent sales representatives. The New York law became known as "Amazon's law" and was quickly emulated by other states. While that was the first time states successfully addressed the internet tax gap, since 2018 states have been free to assert sales tax jurisdiction over sales to their residents regardless of the presence of retailer affiliates.

Emerging black sheep are detected and made known to the affiliate marketing community with much greater speed and efficiency.
