The original iPlayer service was launched in October 2005, undergoing a five-month trial by five thousand broadband users until 28 February 2006. iPlayer was heavily criticised for delay in its launch, rebranding and cost to BBC licence-fee payers because no finished product had been released after four years of development. A new improved iPlayer service then had another very limited user trial, which began on 15 November 2006. At various times during its development iPlayer was known as the Integrated Media Player (iMP), Interactive Media Player, and MyBBCPlayer.
