Companies spend a lot on Cable TV advertising even in this digital era. This is because the fan-following of cable TV has not lost even in this age and so targeting the TV watchers is a safe and wise idea for creating a brand value. However, the advertisements shown on television should necessarily be attractive and creative because then only people will stick to the couch and keep on watching it.
On internet or newspaper, the ads could be just with some good text or audio but for television, those must contain catchy audio-visual matter and no texts. Then only, public would remember the wordings and the brand associated.
