The Hollingbury Industrial Estate is one of the largest such facilities in Brighton; in its early days about 6,000 people were employed, principally in industrial jobs, but in the late 20th and early 21st centuries its focus has switched to commercial and retail development, limiting Brighton's potential for industrial growth. Brighton Corporation laid out the estate on of land around Crowhurst Road in 1950. By 1956, large-scale employment was provided at a bakery, a typewriter factory and a machine tools manufacturer among others. Most of the large factories closed during the recessions of the 1980s and 1990s, employment fell to 1,000, and structural changes started in the mid-1980s with a move towards small-scale industrial units (the Enterprise Estate was finished in October 1985) and then retail warehouses. Asda's superstore opened in November 1987, MFI followed two years later, and other retail units were built in the 1990s. Two large headquarters buildings were vacated in quick succession when British Bookshops left in March 2011 and "The Argus" newspaper moved out of its headquarters in 2012—although the Brighton & Hove Bus and Coach Company signed a contract to move its 1,250 employees into the latter building.
