The channel was planned to launch on 14 May 2009, broadcasting from 10.00am to 00:00 daily, but after broadcasting a promo loop on the planned launch morning, at 10am the channel returned to displaying a "Coming soon" message
The Quest website displays a message reading: "Regrettably we have made the decision to postpone the launch of Quest. Due to a number of commercial factors we have had to make this difficult decision. We did not make this decision lightly and we are working towards launching Quest in the near future. We would like to apologise wholeheartedly to any of you that have been looking forward to this launch."
