In that case, why are producers still swarming like hornets to do the same kind of program? There are two main reasons: First, this kind of show doesn't present any technical difficulties, simply requiring good guests. And second, costs are low. Once the backdrop in the studio is set up, there aren't any new costs.
至於為什麼還是一窩蜂地趕搭現場節目列車，主要有兩個原因：第一，這類節目沒有什麼技術上的困難，只需請好來賓；其次，成本低，攝影棚景搭好之後就沒有什麼其他花費，不用後製剪接。
