Koelnmesse will celebrate the 50th edition of ISM, the world’s largest fair for sweets and snacks, in 2020 with a special anniversary event and an evening honoring exhibitors that haven’t missed a show in its five-decade history.

The "ISM 1971 - 50 Sweets Years" event will offer insight into the history of ISM, and at the ISM Night at the Flora, set for Feb. 2,  tribute will be paid to companies who have exhibited every year. Fair organizers noted the milestone has been a draw for exhibitors, with more than 90 percent of the show space already booked. .
