I don't understand why they have to go from zero breaks to four per hour. Why not just one or two? A break every hour is not too bothersome and sometimes convenient or even welcome. A break every half-hour is sometimes disruptive but not too bad, and certainly understandable if the programs are only an hour to begin with. But an interruption every 15 minutes and the fragmentation starts to become irritating, even if the promotional content is not as offensive as typical television advertising.
