I work part-time at a TV station and from time to time I have to deal with information about the commercials we air. Many commercials are identified with an alpha-numeric code called an ISCI. ISCI stands for International Standard Coding Identification. Many large advertisers use ISCI’s to uniquely identify their commercials. So that Coke commercial you just saw might be called COKE1234. Scheduling the advertising at a TV station is handled by the Traffic manager or director. Find out more about what a Traffic director does at Traffic Director’s Guild of America.
