Market resistance can occur due to several reasons: 1. Customer Inertia: Customers often prefer sticking to familiar products rather than trying something new, leading to resistance against new entrants. 2. Brand Loyalty: Established brands have loyal customer bases that are difficult to shift. 3. Regulatory Challenges: New businesses often face stringent regulations that can impede their market entry. 4. Cultural Barriers: Cultural preferences and habits can also act as a form of resistance, especially in international markets.
