Cable television is a system that delivers television programming to viewers through coaxial or fiber-optic cables. Unlike traditional broadcast television, which uses radio waves, cable TV provides a wider range of channels and often includes premium options for movies and sports. Subscribers typically pay a monthly fee to access various channels, including local, national, and international content. Many cable providers also offer additional services, such as video on demand and digital video recording (DVR), allowing viewers to watch shows at their convenience and record programs for later viewing.
