Does your mortgage payment go down after X amount of time?
Uh yeah, after the escrow has been paid off, in my case 2013.
The difference between pay TV and the other things you cite is they are necessities and satellite/cable is a luxury. Also, I have other entertainment options. I may no longer be a high-end customer, but I pay on time and in full. Plus my departure would figure in churn, something every provider tries to avoid.
The fact that two years ago new customers were offered Free HD for Life struck a bad chord with folks who were with DirecTV for a decade or more and had paid for HD access when it was still a "bakers dozen" count of channels. Part of the reason I dropped below Choice was the $10/mo. HD Access fee. A key factor in choosing DirecTV over cable was that my bill was for programming, not extras. I was being charged $6/mo. for a cable box plus 25 cents for the remote with TWC.
I paid DirecTV $199 in 2001 for Lifetime DVR on a D-TiVo. If DirecTV offered a similar option for Lifetime HD, say $80-$100, I'd consider it. But, the idea that folks who waited until there was a respectable amount of HD with better PQ and locals availability prior to signing with DirecTV having the fee waived I find rather irksome. In some ways satellite has become more like cable and vice versa.
