Inside the CES Vault: What We'll Remember Most From 2015

— -- There's always something at the International Consumer Electronics Show that dazzles and eventually finds its way into homes across the country.

It was the VCR in 1970 that changed the way people watch movies and even gave them the ability to record television shows. In 1981, it was the CD player and camcorder, changing the format we listen to music and preserve family memories.

While those technologies may now be obsolete, they were game-changers at the time for the way they enhanced the way people interact with technology.

Launched in 1967, the first CES was held in New York City and had just 250 exhibitors. As the 2015 CES comes to a close today in Las Vegas, more than 150,000 tech enthusiasts will have seen offerings from more than 3,600 exhibitors.

Spread out among the 2 million square feet of hotel and convention center space, attendees interacted with robots, personal drones and off-the-wall gadgets, such as a levitating speaker and skates to help users walk faster.

While there wasn't any consumer-ready technology among the show that stood out as a game-changer, this year's CES will be remembered for providing an incredible look at how humans and cars may one day interact.

Patrick Moorhead, a technology analyst at Moor Insights & Strategy, told ABC News from Las Vegas that he was floored by the "awesome car technologies."

"We got a great look at car technologies for the near future, which revolved around the car being able to see what is around it and react to it," Moorhead said. "The car can self-park, but can also, through computer vision, identify people, signs, cars, trucks and even identify ambulances."

He said he was especially impressed by the presentation from chip maker NVIDIA, which announced it is developing a technology that will allow humans to tell their car to "go park yourself."

The DRIVE PX computer harnesses the power of two of the company's Tegra X1 super chips. While the technology is still in development, it provides an insightful glimpse at how humans and cars may interact in the future. It's something we can remember seeing first at CES 2015.
