The meaning of being saturated or reaching the point of saturation in the business terms is the time in which a market does not generate any more demand for a certain market. This may be due to increase competition, decrease need or the product became unusable. For sellers, saturation means two things, first is that this is the chance for you to give your business a makeover. You can level up your products or service or try a new strategy for your business. The endpoint is that you need to diversify so that the customers will not get tired of the same product of service all over again. If you observed that with all the things you possibly did to keep the product or service growing, you haven't seen any change the market demand then the second thing you may want to do is to stop your business because it will only be a waste of time, research and money.
