Epsom Derby 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. Investec became the sponsor of the Derby in 2009, and the current sponsorship deal runs until 2022. The race was previously backed by Ever Ready (1984–94) and Vodafone (1995–2008). Epsom Derby is also referenced in the recent popular BBC television series "Peaky Blinders", set in the 20th century.
