Intel launched its successful "Intel Inside" ingredient branding campaign in 1991 to promote its microprocessors. The campaign involved convincing computer manufacturers to display the Intel Inside logo in their marketing materials. This helped address consumer uncertainty about microprocessor quality and established Intel as a symbol of reliability. By collaborating with partners and reducing costs through volume discounts, Intel was able to substantially increase its brand awareness and market share while maintaining high advertising exposure. The campaign proved highly successful for Intel, growing its market capitalization five-fold by 2003 and ranking as the sixth most valuable brand in the world by 2001.
