Eventually the OCCC staff modified and adapted Bliss's system in order to make it serve as a bridge to English.[2] (2009, p. 189) Bliss' complaints about his symbols "being abused" by the OCCC became so intense that the director of the OCCC told Bliss, on his 1974 visit, never to come back. In spite of this, in 1975 Bliss granted an exclusive world license, for use with disabled children, to the new Blissymbolics Communication Foundation directed by Shirley McNaughton (later called Blissymbolics Communication International, BCI). Nevertheless, in 1977 Bliss claimed that this agreement was violated so that he was deprived of effective control of his symbol system.[3]
