I haven't seen any popular company that stops advertising because their business is now popular. It's even when they are very popular they have more money to pay for heavy influencers to promote their brand. Our telecommunication companies here are very popular but they are paying celebrities millions to promote their brand all the time.
I may not say that they have stopped advertising products completely. However, I have noticed many popular businesses not advertising their business that much as they used to do before. This also includes many big brands. Having said that, I think that even big businesses should advertise their businesses on social media.
