The little heard-of The Documentary Channel has doubled its subscriber base since its inception. This has allowed it to grab the attention of DirecTV and has agreed to share its rights with the satellite giant. I’ll be honest, as I’ve gotten older and wiser, I have been drawn to more documentaries. I like seeing the “making of” or the back stories of significant events or people that have influenced the world. Now with their new agreement, things could take off for the small channel.
