In an initial five-year deal worth £500,000, Sharp Electronics became the club's first shirt sponsor at the beginning of the 1982–83 season, a relationship that lasted until the end of the 1999–2000 season, when Vodafone agreed a four-year, £30 million deal.Vodafone agreed to pay £36 million to extend the deal by four years, but after two seasons triggered a break clause in order to concentrate on its sponsorship of the Champions League.

To commence at the start of the 2006–07 season, American insurance corporation AIG agreed a four-year £56.5 million deal which in September 2006 became the most valuable in the world.At the beginning of the 2010–11 season, American reinsurance company AON became the club's principal sponsor in a four-year deal reputed to be worth approximately £80 million, making it the most lucrative shirt sponsorship deal in football history. Manchester United announced their first training kit sponsor in August 2011, agreeing a four-year deal with DHL reported to be worth £40 million; it is believed to be the first instance of training kit sponsorship in English football.

The club's first kit manufacturer was Umbra, until a five-year deal was agreed with Admiral Sportswear in 1975.Adidas received the contract in 1980, before Umbro started a second spell in 1992. Umbro's sponsorship lasted for ten years, followed by Nike's record-breaking £302.9 million deal that will last until 2015; 3.8 million replica shirts were sold in the first 22 months with the company. In addition to Nike and Aon, the club also has several lower-level "platinum" sponsors, including Audi and Budwieser.
