Advertisement on TV

Nowadays there are more and more advertisements on tv ,they appear either before a TV program or after it ,and sometimes even inserted between episodes of a TV serial plays,and the time of which is becoming longer and longer ,which is so boring ,and many watchers cannot wait but switch to other channels. But why this phenomena has appeared ,the reason may be two .At the first place ,it is a methodfor businessmen in such a highly competitive market to make their goods known by customers ,which will improve the sales amounts .At the second place ,it is a chance for the tv station to earn money to support their programs . If i am given the chance to meet the leader of tv station ,i would like to suggest them decrease the amounts of the advertisements relatively .Maybe doing this will lose some profits, but instead,the audience rating will be improved largely.
