Why are entry level dslr camera not full frame?

There are full frame dslr’s like the D700 and 5D mark II but why did the camera industry decided to make sensors smaller than 35mm film slr’s. I know it’s still pretty big much larger than point and shoot cameras but why didn’t they stick with 35mm or close to that? Film point and shoots sensors were mostly bigger than digital point and shoots too right?
I think I missed sensor with something else. Isn’t the mirror thing where light that goes through the lens hit the sensor?
*is the sensor.

Full-frame sensors are more expensive and not needed in entry-level DSLRs. Film cameras do not have sensors- they use film!
because "entry level" is more or less a synonym for "inexpensive" or "low cost"
Cost is the primary reason.
In the film equivalent, there were a lot of compact rangefinder 35mm film cameras, those made by Nikon, Canon, and other camera manufacturers.
Even then, there in the last days of film, the APS film cameras had been gaining some popularity. The cropped DSLRs from Nikon and Canon are known as APS sensors as they are closer to the size of APS film rather than 35mm film.
Kodak however had many cameras made that were smaller film "footprint", like the 126 film and 110 film cameras.
Bigger sensors cost more money… It’s something that’s not just in the world of DSLRs either. The same goes for point and shoot cameras as well as video cameras. TV studio cameras deliver such a great picture because they have big sensors. They can also cost $80,00 or more… Some of the larger non full frame sensors can deliver professional results especially when you know how to bring out the colors in photoshop.
Also the better the "glass" or lenses in in front of the sensor or film, the better the image. Lenses can effect the sharpness, depth of field and color of an image.
The mirror is only used to reflect the image from the lens into the camera’s viewfinder on DSLRs and film SLRs. Film cameras do not use sensors, they use film to capture their images. The APS system was popular for point and shoots from the late 90s. APS film is a little smaller than 35mm film. APS never really became a huge success because digital photography took over shortly after it was introduced.
One more note… Bigger film or sensors perform better because they have more pixel area or film resolution. Larger sensors can be less noisy and are more sensitive in low light situations.
