Klokhuis is an educational show for early teenagers produced by Omroep NTR of the Netherlands. The show started in 1988. It is broadcast every weekday at 18:25 on Nederland 3 and lasts about 15 minutes. The subjects vary wildly, but often use an angle that is uncommon in other shows, which also makes it popular with adults. Quite often, factories are visited, where a complete production process is explained. The serious parts are interspersed with funny sketches, which sometimes have aspects that only adults would understand, whilst still remaining funny for children. After 25 years, almost everybody in the Netherlands knows the show and generations grew up with it. It has become a so-called institution, which not much tv-programs have achieved.
