Product names are made up of up to six characters. The first letter identifies the firm marketing the product (M, S, L or H). The second letter must be an 'O' for a Sonite or an 'E' for a Vodite. The other characters can be letters or numbers and can be freely chosen by each firm to generate different product names.
For instance, products SOFT and SOLO would be Sonites marketed by firm SUPER, while MEGA and MEMO would be Vodites marketed by company MASTER. All new products must follow these conventions and must have different names. The selected name has no influence on the market response to the product.
