I'm afraid I've fallen behind a little as I'm travelling but I have already implemented this strategy, by approaching other people in my industry who have TV related businesses and done an interview with them. They've were delighted to be asked, their businesses were of direct interest to my target audience and now I've got some good karma saved up (and the potential to develop JV/affiliate partnerships down the line).
I wanted to share a slightly different post - How to Get Your Idea on TV as a Truly Independent Producer - which profiled an ex-colleague who had just launched his first independent project.
He is part of my target demographic (so it's good for me if he spreads the word about my blog) and his story was relevant to both professional TV producers and those just starting out as indie producers, so it was a story which had broad appeal for my readers. I have a 'featured post' section on my front page where I put key articles once a week, and are therefore visible for seven days (other posts get rotated off the front page after only a day or so in the spotlight), so my interviewees get maximum exposure.
I've found that I can normally link to other posts too so they will draw my readers into my archives. Once I'd posted this article, I realised I had extra interview material that I'd not been able to use in the original post, so I posted a second article and got two for the price of one (plus more inter-post links) - Alom Shaha's Top Tips for TV Development Success
