KDD made history in 2020. It was planned to be held in the San Diego Convention Center in an environment that would attract a large number of participants, companies to an attractive location. The program planners also made a concerted effort to broaden the intellectual scope of the forum as well as participation by diverse communities. In particular, the conference planned for offering complimentary full-time daycare to enable participation by women and parents with young children. The emergence of COVID-19 disease in March, however, caused considerable uncertainty leading to a final determination for a first-ever entirely virtual conference. This shift was dramatic at multiple levels since KDD is more than a meeting of presenters and their audience. It is also a place for demonstrations, chance encounters and a very engaging floor exhibition with its own ongoing events. Without exhibitors, their sponsors, and missing attendees, KDD won't be KDD. And it will also have a significant financial liability to the conference for the event contracts already in place. With significant cooperation from ACM and support from SIGKDD Executive Committee the team not only avoided financial impact but emerged with a net positive financial outcome even after reducing the registration fees by over 80%.
