The X Factor in the UK has been subject to much controversy and criticism since its launch in 2004. This has included allegations of conflict of interest, voting irregularities and overcharging, product placement for sponsors, staging scenes, use of pitch correction technology, and exploiting vulnerable contestants. The series has also been criticised for developing singers as marketable products rather than creative individuals. As of April 2020, there have been fifteen completed series broadcast on the ITV network, as well as spin-offs The X Factor: Celebrity (2019) and The X Factor: The Band (2019).
