This seems to be true of many major trade shows and conferences. The Consumer Electronics Show gets wall-to-wall media coverage. E3 (the big North American computer/video game show) is an immense media spectacle. The major auto shows in the US sell public-access tickets; people within the industry get their own admission tier and do their business in private suites. Even some of the food industry conferences end up getting time on TV. And because of this the exhibitors at all these shows have to do their best to make their pitches soundbite-ready and consumer-focused since these are frequently the first or only opportunities many companies have to get their products known to the public without expensive ad buys. I don't think this particular trend is going away.
