By the early 2000s, the number of consumer electronic devices in most homes greatly increased, along with the number of remotes to control those devices. According to the [[Consumer Electronics Association]], an average US home has four remotes.{{citation needed|date=December 2011}} To operate a [[home cinema|home theater]] as many as five or six remotes may be required, including one for cable or satellite receiver, [[VCR]] or [[digital video recorder]] (DVR/PVR), [[DVD player]], [[Television|TV]] and [[audio amplifier]]. Several of these remotes may need to be used sequentially for some programs or services to work properly.
