[EX Q]: Person1: Sir , I am very glad to tell that we have successfully registered the trademark for our new product . It is the time to think of some effective promoting strategies . We are beginning to get more attention from overseas .
Person2: Well done , Fred . Do you know something useful for our promotion for our I-series ?
Person1: OK , Let me see . I suppose we must strengthen our promotion , because our brand is still new to some consumers . Maybe we should start our advertising program with our local and overseas distributors simultaneously , because they stand on a better position for selecting the best ways to advertise in market places . Besides , the advertisement fund can encourage them to spend more attention on advertising our products .
Person2: That is a good idea to start with . I also think the mass media is also a good approach for advertising .
Person1: Yes , the mass media has wider influence . One of my classmates works in an advertisement company . I can get help and inspiration from him . And we can also try some less expensive approaches of advertising , such as on-line sales . Personally , I prefer to the on-line sales , for it is cheaper , faster and wider .
