In the 1870s, the steam-driven rides were introduced. They were located at the Tattenham Corner end of the grounds and the fair was on for ten days and entertained hundreds of thousands. During the latter half of the 20th century, Derby Day became less popular and the race was moved from Wednesday to Saturday in 1995 the hope of reviving high attendance. As the number of people attending the fair dwindled in the face of competition for attention and changing tastes, its length was reduced from 10 days to three or four.
