A、To celebrate the successful launch of the new product. B、In order to create a favourable impression with the media. C、Because

M: Right, let’s get on to the marketing strategy.
W: Well, the marketing team believe that we should launch the product at the International Trade Fair and invite the media to a party on the evening of the 22nd.
M: The idea being that the media will be more favourable to our product if we give them some food and drinks before they write their stories.
W: Exactly! But to be honest, our product should really sell myself.
M: Well, a little marketing and promotion won’t hurt. We’ll be giving demonstrations at the trade fair, right?
W: Yes, all day long. It’ll be a little repetitive, but ensure that everyone has a chance to see it in action.
M: Good. Did you get the budget accepted by the Board of Directors?
W: I did. We’ve got the full amount we asked for. That means we can go ahead with the newspaper and Internet ads.
M: And the ads in the specialist magazines. I think that those will get us the bulk of our orders.
W: I agree. They’re very expensive, but they’ll be worth it. I’ve also placed the order for the brochures. The printer will have them done by the end of next week.
M: That was a good idea of yours to have the brochure prepared even before we got the budget approved. If we hadn’t done that, we’d never have been able to get the brochures printed in time.
W: Well, it was clear that we’d get the budget we asked for. The board wasn’t going to risk having our product flop because of a lack of publicity, was it?
M: I wasn’t entirely sure we’d get the full budget, to be honest. I’ve seen the board fail to put enough money into marketing and promotion before.
W: Really? How could they be so short sighted!
M: It’s amazing, isn’t it?
W: Tell me about it over a drink. It’s been a long day!
M: You’re right. I’m really looking forward to the weekend.
W: Me, too. We’ve got everything ready to go. I might even come in late on Monday morning!
