I noticed that it was no longer listed as being broadcast the other day whilst channel surfing and have found this on it's Wikipedia page:
Teachers TV - Wikipedia, the free encyclopediaQuote:
In March 2010, Ed Balls, then Secretary of State for Children, Schools and Families (DCSF) axed the broadcast deals in place with Freeview, Freesat, Sky and Virgin Media in a bid to save the channel around £1m in carriage costs annually. It closed on Freeview first on 21 July and Freesat, Sky and Virgin followed on 31 August 2010. Online availability was unaffected by the change.
The online content and site is still available though, but without the TV channel I wonder how much life is left in it?
