Why is there an ????? of ???????? It’s for three possible reasons (aside from the damage to the neshomo): ?? ?????, ???????, ??? ?????. At least two of those three (but probably not ?? ?????) are just as applicable by an image as by a live person. The difference is the degree to which there is ????? ??? ???; all things being equal, it’s more of a problem with a live person. But we’re talking about images and ideas which are far from innocuous, and clearly are designed for, and have the effect of, ????? ??? ???.
So anyone, to quote the ???? ????, who is “???? ?? ????”, will recognize that looking at a typical television program or movie (of course there are some exceptions) is violating at least one or two of these issurim (and, he says, others as well).
Aside from the images, there is also the subject matter. See, for example, ???”? ????? ?????? ???? ??? ?”? ????? ?”? – ? for cases of ??????? which are ???? despite no ??? being there. Typical secular entertainment, even the programs which are officially “clean”, contain ????? ??????.
