How this is ranked

Shows are ranked by the number of companies on the latest exhibitor list, taken from the organizer's directory (linked as source). Shows with fewer than 25 exhibitors are left out. "vs prior edition" is the change from the previous edition's list, where available. Where that list is no longer online, it compares the exhibitor counts the organizer published for its last two editions, marked "organizer figures" and linked to the report. Attendance is the organizer's published figure for the year shown. Sponsors are counted separately from exhibitors. Select a column heading to sort.
