There are still a significant number of analog TVs, VCRs, etc. out there.
For the next few years, the FCC needs to encourage or require that manufacturers slow down the race to "planned obsolescence."
FOR THE TIME BEING, if I were the FCC I would require that manufacturers who provided any tuning capability at all and which market their devices as being able to receive OTA HD signals provide either analog-channel-3-in or offer a free adapter to any customer who asks if they do so within a reasonable time (a year, or the warranty period if less, for most products).
I would also require FOR THE TIME BEING that any device that is marketed as being able to "play to your TV" and which produces analog output (RGB, Svideo, component video, etc.) either provide channel-3 out or provide a free adapter as above.
Within 5-10 years these requirements should be lifted completely, and the "free adapter" requirement should be replaced with "make an adapter available at a reasonable cost, unless such adapters are already widely available at a reasonable cost" much, much sooner than 5 years.
As an example, if "channel 3 to component video" and "component video to channel 3" adapters are widely available for under $10-$15 each by the time the "free" requirement is lifted, this regulatory burden on manufacturers that provide component-video-in and -out will be pretty much nil beyond filling out some paperwork.
