Typical big business.. They see the little guys getting all the attention then they swoop them up, profit from them, and grow larger networks. Just like banks, etc. All in the name of the almighty dollar.
I personally like the old Roadkill on Youtube. But that's also now a thing of the past as big biz got their hands on them and now you have to pay to watch MotorTrendTV or wait months to catch it for free.
