re: TV Shows and the "Coming Up" Tease Before Commercial Breaks

VH1 perfected this in the 90's with their behind the music series. You have four commercial breaks in the hour. You do a "coming up" tease at the end of each segment and a "recap" at the start of each segment. If each tease/recap is :60, that's eight minutes less footage and content that you have to come up with. Throw in your opening and end titles and you've got 20% of your show that is recycled content.
