Week In Week Out - Changing the channel.

As the channel celebrates its 25th anniversary, Week in Week Out looks at the future of the Welsh channel S4C. Presented by Richard Evans. Following the switch off of the analogue tv signal in Wales in 2010, S4C will only broadcast programmes in the Welsh language. Its analogue channel currently shows the best of Channel 4 programmes along with its Welsh language output. This has led to calls by the Labour MP for Rhondda, Chris Bryant for S4C to transmit programmes in English after 2010 to protect its future.
