Viz Comics issues one to four was published in November 1983 as issue 10½. After a few years of steady sales, mostly in the North East of England, circulation had grown to around 5,000 by December 1984. This may have been boosted by the appearance in the BBC2 documentary series 'Sparks' (episode 4 'The Young Guns') which first aired in March/April 1984 and was repeated on BBC1. A further special edition was issued in May 1985 as issue 12a. What had begun as a few pages, photocopied and sold to friends, became a publishing phenomenon. To meet the demand, and to make up for Brownlow's diminishing interest in contributing, freelance artist Graham Dury was hired and worked alongside Chris Donald. As the magazine's popularity grew, the bedroom became too small and production moved to a nearby Jesmond office. Donald also hired another freelance artist, Simon Thorp, whose work had impressed him. For over a decade, these four would be the nucleus of Viz. In 1985, a deal was signed with Virgin Books to publish the comic nationally every two months, starting with the 13th issue, dated August 1985. In 1987, the Virgin director responsible for Viz, John Brown, set up his own publishing company, John Brown Publishing, to handle Viz. Sales exceeded a million by the end of 1989, making Viz for a time one of the biggest-selling magazines in the country. Inevitably, a number of imitations of Viz were launched, but these never matched the original in popularity, and rarely in quality. Sales steadily declined from the mid-1990s to around 200,000 in 2001, by which time Chris Donald had resigned as editor and passed control to an "editorial cabinet" comprising his brother Simon, Dury, Thorp and new recruits Davey Jones and Alex Collier. In June 2001, the comic was acquired as part of a £6.4 million deal by I Feel Good (IFG), a company belonging to ex-Loaded editor James Brown, and increased in frequency to ten times a year. In 2003, it changed hands again when IFG were bought out by Dennis Publishing. Soon after, Simon Donald quit his role as co-editor, in an attempt to develop a career in television. In July 2018, Dennis Publishing were bought by Exponent, a British private equity firm. Much of the non-cartoon material such as the newspaper spoofs are written by the editorial team – Graham Dury, Simon Thorp and Davey Jones
