According to The Wall Street Journal, Yahoo! is negotiating with Apple, the purpose of which is to better integrate search engine services into the iOS operating system.
Such a deal would be beneficial for both companies. Yahoo! would be able to increase the attendance of their services, and Apple become less dependent on services Google. However, will Tim Cook's company become the default search from Yahoo! one can only guess, because its quality does not meet modern standards.
By the way, Apple is already actively using two Yahoo! — Yahoo! finance (finance) and Yahoo! weather (weather). It is likely that now the list will increase.
Most likely, the companies will be able to agree. However, experts doubt the usefulness of this deal for Yahoo!, believing that it will not be able to solve all the company's financial difficulties.
