In Las Vegas, in 1975, Borgnine learned of a cactus-based face cream made from a formula by a Mexican family and bought worldwide distribution rights. By 1977, the revenues for her company, then called Tova9, were about $500,000; by 1981, they were nearly $2 million. In 1984, Borgnine published The Tova Difference: A Promise of Lasting Beauty, with Elaine Trebek.
