October 2012 a selection of those comments was posted on Ceefax. Comments were edited and put to air by a team of four journalists based at Television Centre in London. The system displayed one message at a time, and usually showed several tens of messages throughout each hour-long episode. The system's popularity sprang from its mix of serious and light-hearted comments. On average, around 3,500 texts are received during each hour-long programme, although 12,000 texts were once recorded in one frantic programme in 2004.
