 At the time, advertising on Sundays still wasn't yet allowed, mainly in part due to the heavy influence of the churches.In 1991 advertising on Sundays slowly began to take place.With the plan to abolish the licence fee in 2000 due to the excessive collection costs and to pay for public television from government funds, income tax was increased in the late 1990s and maximum run time of commercial breaks was extended to 5 and 7 minutes.
