Question: Person1: There are advertisements everywhere here in hong kong . The city is so bright at night , with all the neon signs .
Person2:I like it . It makes the city feel alive . I like all the different colors and I like the billboards with eye-catching pictures and slogans .
Person1: I think that there are too many of them . I think that companies spend far too much money on advertising . They should have lower prices instead . Then they would see more .
Person2:I see your point , but if companies didn ' t spend money on advertising , no one would hear about their products . I agree that some form of advertising can be annoying . I don ' t like it when people try to give you leaflets with information about products you have no intention of buying .
Person1: I really hate receiving spam . I also dislike having to listen to advertisements and jingles when they are broadcast in stores or on the subway .
Person2:Yes , that annoys me too . With billboards , you can look away , but with broadcasts , you can ' t avoid them . I like the way that advertising agencies use comedy in their campaign .
Person1: I like that too . I don ' t like the way that advertising campaign often tell you if you don ' t buy a certain product , you ' re not cool or modern or efficient or something .
Person2:That kind of advertising seems to be very common with brand name products . They are always trying to maintain brand loyalty .
