Google and Microsoft used some of Apple's well-known user pain points to promote their own services in two separate TV and YouTube ads this month, CNN reports.

On Tuesday, Microsoft went after Apple by pitting its new Surface Pro 4 tablet and Cortana smart assistant against the iPad Pro and Siri.

Microsoft and Apple have a history of going after each other through marketing campaigns: For years, Apple ran a series of anti-PC commercials starring Justin Long and John Hodgman. And this year, Microsoft has been pushing its "PCs can do more than Macs" message in commercials.

Google took the first -- and a more gentle -- stab at the Apple in the beginning of August with a 60-second spot about its Google Photos app.

To show off its photos backup service, Google's commercial includes several scenes of smartphone users about to capture a Kodak moment. As they're about to take a picture -- when a birthday girl starts to blow out her candles and a humpback whale jumps out of the water -- a pop-up appears to stop them: "Storage Full. There is no more room on your phone."

While the design and message resemble what iPhone users see, it's not exactly the same. Even so, it's clear Google is highlighting the iPhone's limited storage problem that it hopes to solve.
