Apple launch events usually involve new products and product improvements, along with higher prices for some devices. But at the launch event this week, the company announced a number of new products without raising prices. In the case of Apple’s low-end iPhone, the price was lowered from the current model. Apple also reported that the price for its new video service will be well below competing companies like Netflix and Disney Plus. And the company said it plans to launch a video game subscription service on September 19. Industry experts say Apple’s price-freeze and expansion into a pay video service appear to be an answer to a drop in iPhone sales worldwide the past few years. It has become more difficult for Apple to get people to pay for new devices that sell for $1,000 or more. This year, iPhone shipments are down 25 percent.
