With ticket sales the major source of income, a successful marketing strategy is the sine qua non of CLOC's survival and growth. CLOC's comprehensive computerised database includes information on over eight thousand preferential patrons and is the basis for on-going market analysis, direct mail and telemarketing, customer surveys, policy reviews and strategic planning.

CLOC advertises in city daily papers, suburban weeklies, theatre magazines, trade journals, programs and other relevant publications. Wide use is also made of handbills, postcards and radio interviews. Finally, CLOC actively encourages the attendance of critics and values the contribution they make in selling productions and in assisting CLOC to achieve the highest possible standards of creativity, originality and presentation.

Over the years, the CLOC program has evolved from a flimsy gestetner produced, hand and type written give away into a graphically designed, printed, souvenir sales document containing professionally researched and written copy, photographs and advertising.
