Watching programs(specially movies) on TV and time management

Nowadays TV channels display lot of advertisements during their programs. The advertisements will be more if it is a new movie or a program with higher TRP. I always used to get frustrated to wait for the advertisements to finish as it extends for a long duration. If I change the channel, I had to check once in a while to check whether the program/movie has resumed. Recently, after a lot of observations I have found out that TV channels a pattern in displaying advertisements. They set a fixed duration for advertisements and programs, for example 8 minutes of movie and 6 minutes of advertisements or any other pattern. This will be almost constant till the end of movies. We can check for the pattern during the first half-an-hour of the movie when the first break comes and ends. Then we can exactly tell at what time the next advertisement break comes and it ends. So, we need not wait or check once in a while to determine if advertisements have ended or not and we can directly tune into the channel exactly when the advertisement break ends. This idea works well in most of the cases except some such as a news headlines in middle. That's all for today. Enjoy watching TV without getting frustrated. Hope you enjoyed my post.
