1. If a TV supported *only* 1080p, any video source you connected to it
would also have to support it.
2. A video-scaling circuit is dirt-cheap compared to the cost of the panel
and the back-light.
3. Calling all those resolutions "HD" lets them make TVs with lower
resolutions and still market them as "HD".

Making a high-resolution panel is expensive. Making a large panel is
expensive. Making a large high-resolution panel is *really* expensive.

Most movies are widescreen. However, most movie producers traditionally
took care to make the movies easily convertible to 4:3 (typically through
Pan&Scan) specifically because TVs used to be in that format.

That may be true for you, but you really need to stop assuming that
everyone in the entire world has the same behavior and preferences as you.

Once again, cost. Some networks save money by reusing the same tapes they
have been using for decades. Since those tapes were already prepared for
4:3, that is what you get. Newer movies, and also older movies shown by
less stingy networks, are almost always shown in widescreen.
