There are 16 minutes of commercials per hour from 8 A.M to 11 P.M
First, we have to find out how many hours is 8 A.M to 11 P.M 
The hours are: 8, 9, 10, 11, 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11. 
So, it is 16 hours from 8 A.M to 11 P.M 
Then, we multiply multiply 16 by 16 to find out how many minutes of commercials are in 16 hours. 
16 x 16 = 256
So, there is 256 minutes of commercials in 16 hours. 
Lastly, multiply 256 by 365 to see how many minutes of commercials are in one year. 
256 x 365 = 93,440 
Therefore, there are 93,440 minutes of commercials in a year.
