In 1984, Wall founded Radio Vision International, a company which "pioneered the business of international music video licensing." Convinced of the opportunity that increasing broadcast options would provide, he developed the idea for Radio Vision while attending an annual television conference in Cannes. His assessment was accurate, and Radio Vision was quickly profitable, distributing 60 music television programs internationally and building a library of more than 125 music and specialty programs. The company's financial success allowed Wall to work with non-profits, providing Radio Vision's services on a break-even basis for benefit concerts such as Live Aid, USA for Africa, the Human Rights Now! Tour, the 70th birthday tribute to South African activist Nelson Mandela and the annual Prince's Trust Rock Gala, sponsored by Britain's Prince Charles, to raise money for underprivileged children.
