Magazines offer advertisers extensive choices of readership and frequency. Consumer magazines cover a wide range of interests, including sport, hobbies, fashion, health, current affairs and local topics. Many business and trade magazines provide coverage of specific industries, such as finance or electronics. Others cover cross-industry topics, such as communications or human resources, while still others focus on job-specific areas, such as publications for executives, marketing professionals or engineers. Publishing frequency is typically weekly, monthly or quarterly. As with newspapers, advertisers can take advertising spaces from classified ads to full page ads in black and white or color.
