What is the ruling on a woman observing 'iddah (waiting period) watching television, and what are the programs she is permitted to watch?

It is not permissible to watch reprehensible things shown on television, whether for a woman in her 'iddah or for anyone else. Although television is a double-edged sword, its harms today outweigh its benefits. Therefore, it is safer for a woman in her 'iddah and for others to avoid it.
