Only 9% of companies use sound branding but Intel has successfully used its distinctive startup sound for years. The Intel Inside campaign aimed to educate consumers about Intel's superior microprocessors without technical jargon. It helped Intel differentiate its products from clones, increased awareness of Intel logos from 24% to 94%, and boosted worldwide sales 63% within a year of the campaign. The strategy established Intel as a reliable, high-quality brand and propelled it into the top 10 most valuable brands by 2002.
