WHEN the television had come to Pakistan in 1964, its transmission time was limited to a few hours in the evening. With the passage of time, more channels came along, and today there are about a hundred of them functioning round the clock. Almost every channel telecasts programmes for eight hours daily, and the content is re-telecast twice to complete the 24-hour cycle. There are only two options: first, the programme schedule should be extended to 12 hours and repeated only once for the next 12 hours. Second, the present eight-hour cycle should be repeated only once, and not twice, to save time and electricity.
