Not only is Crackers diagram brilliant, but it’s also 100% accurate. You could learn a lot from it!
On a side note, this thread has reminded of something that I meant to post on here a few weeks back… I’m not sure how product placement works in the US, but here in the UK, it was never allowed. This has now been lifted and production companies can now advertise products within their programs if the product manufacturer is paying them. If they do this, they have to have a “P” logo at the start of their programs, to inform the viewer that they are trying to sell them a product during the program.
