Pay television
Pay television returned to the terrestrial platform in March 2004 when Top Up TV launched. The BBC and Crown Castle multiplexes were at the time not allowed to broadcast pay channels, so the new service broadcast on multiplex A and Channel 4's half of multiplex 2. The autumn of 2004 saw the launch of two new free-to-air entertainment channels; ABC1 in September and ITV3 in November. ITV3 was the replacement for Plus on platforms other than Freeview.
