Advertising costs
Broadcast time slots cost advertisers different amounts: a prime time slot during The X Factor (ITV1, prime time, Saturday night) will be more expensive than broadcasting in a slot during Countdown (Channel 4, afternoons, week days).
The most expensive advertising time slot is during The X Factor finals when 30 seconds costs around £200,000.
Both Asda and John Lewis have used this time slot to premiere their Christmas campaigns
Guinness and Chanel have produced some of the most expensive adverts of all time.
In 2007, the Guinness advert entitled Tipping Point cost £10 million.
The most expensive advert ever made was produced by Chanel, and directed by Baz Luhrmann, for Chanel No. 5. Featuring Nicole Kidman, it was two minutes long and cost an estimated £18 million.
