Explain Budget in advertising?

When considering advertising as a marketing communication method, companies need to balance the cost of advertising–both of producing the advertising pieces and buying placement—against the total budget for the IMC program.
The selection and scheduling of media have a huge impact on budget: advertising that targets a mass audience is generally more expensive than advertising that targets a local or niche audience.

It is important for marketers to consider the contribution advertising will make to the whole. Although advertising is generally one of the more expensive parts of the promotion mix, it may be a worthwhile investment if it contributes substantially to the reach and effectiveness of the whole program.

Alternatively, some marketers spend very little on advertising because they find other methods are more productive and cost-effective for reaching their target segments.
