Advertisements were once written and arranged by the individual or company selling a good or service. Today, most national advertising, and much local advertising, is prepared by advertising agencies. Modern firms split up the different tasks of advertising among workers specifically trained to handle the writing, design, and overall appearance of ads. Copywriters and their assistants write the words of advertisements, including the written text in print ads and the spoken words in radio and television ads, which are also called spots.
