There has always been bookers, but I guess now the term is writer. With so much talent in organizations now, the booking cannot come down to one man as it was in the 70's and 80's. You had between 10-20 "main" guys in each promotion with them basically knocking around jobbers on TV. With the emphasis on storys and back-ground pushing towards a match, there has to be a "booking" team. Basically it is worked as a soap-opera now.
