Whilst not properly described as T shirts, Replica Football shirts, normally replicas of the sports shirts worn by athletes, are commonly found in the Football market, with increased popularity after the commercialization of football in the 1990s. With the rise of advertising in the mid 20th century, sponsors' logos began to appear on the shirts, and replica strips were made available for fans to purchase, generating significant amounts of revenue for clubs.
Since the mid-1970s, Football shirts have been made of lightweight polyester, although prior to this they were typically of a heavyweight cotton design.
In the United Kingdom, several clubs have been accused of price fixing, and Manchester United were in fact fined in 2003. The high prices, and the fact that new designs are brought out each season for many clubs, mean that shirts are often the subject of satire among football fans, but many still consider it an obligation to wear them. Many Newcastle United and Manchester United fans buy their clubs' black and white striped and red and white shirts, respectively. The prices have also led to fans buying fake shirts which are imported into the UK from Thailand, Malaysia, and Far East Asia; many sellers on eBay now indicate that their shirt are genuine.
