PC demand helps to boost Intel revenues

Intel chief executive Brian Krzanich is getting help from other corporations as they upgrade their office machinery.

The world’s largest semiconductor maker yesterday raised its second-quarter revenue forecast and said annual sales will increase for the first time since 2011, buoyed by improving business demand for personal computers.

The higher forecast provides another hint of optimism in the PC industry, where Intel gets most of its revenue, after two straight years of declining global shipments.
