F or five years, one of Advance Concepts most important functions at the TCT Conference has been the videotaping and duplication of the majority of the meetings for post-event sale and distribution. Offering DVD and VHS formats, as well as international standards conversions, ACI offered a selection of over 300 hours of tape each year, encompassing more than 77 sessions, lectures and live case demonstrations. Duplicates were shipped to six continents, all within a few weeks after the close of the conference.
