Explanation:

Permission marketing is a concept introduced in a book of the same name in 1999 by marketing expert Seth Godin. Permission marketing is a non-traditional marketing technique that advertises goods and services when advance consent is given.
Traditional methods of marketing often revolve around the idea of interruption – whether it is a television advertisement that cuts into a TV show, or an internet pop-up that interferes with a website. According to Godin, such methods (often referred to as “interruption marketing”), have become less effective in the modern world, where consumers are overloaded with information.

Interruption marketing is essentially a competition to win people’s attention.[3] In today’s world of mass-marketing, people are overloaded with advertisements that compete for their limited time and attention span. Yankelovich, Inc claims the average consumer comes into contact with 1 million advertisements per year – or nearly 3000 per day. When there is an overflow of interruptions, people’s inevitable response is to disregard them, tune them out, and refuse to respond to them. Such traditional methods of marketing are more difficult and costly to attain the same outcome.
