Being famous doesn't require excessive marketing
That's incorrect. Considering the competition in each industry, a project or brand that doesn't constantly advertise or promote itself starts to fade out of the limelight. This makes it a necessity for every brand, project, or firm to keep promoting itself and its products and run giveaways and promotions to keep its customers engaged and attract new customers to their business.
Do you know that every company, firm, or project has a specific monthly revenue budget dedicated only to promotional campaigns and advertisements that run throughout the month? They hire marketing experts to plan and execute their marketing campaigns; after all, marketing makes a brand or project stand out.
Companies that maintain quality will undoubtedly retain their customers, but marketing is essential to keeping the business flowing and attracting new customers, no matter how popular the company or project.
