Since 2009 part of the Portmeirion Group, Royal Worcester remains in the luxury tableware and giftware market, although production in Worcester itself has ended. The enterprise has followed the pattern of other leading English porcelain brands, with increasing success during the 18th and 19th centuries, and a gradual decline during the 20th century, especially the latter half.By the start of the twentieth century sales were in decline and in 1930 the factory went into recevership.CW Dyson Perrins bought the factory in 1930 and, under the guidence of J Grimson, set about reforming production there.This is discussed in detail in Appendix III of Flight & Barr Worcester Porcelain by Henry Sandon.During this period, the factory was in poor repair.
