CD-ROMs were created in 1985 by Sony and Philips. They store large amounts of digital data, including software programs, video games, and multimedia applications. CD-ROM discs have the same physical structure as audio CDs, using a thin aluminum layer and polycarbonate plastic. Disposable cameras were meant for single-use and included installed film, making them convenient to carry for photography. Roller racers were scooter-like toys ridden by moving back and forth while holding handlebars. Pogo balls allowed jumping up and down on a platform attached to a ball in the middle.

The Berlin Wall was built in 1961 to prevent East Germans from fleeing to West Berlin and was stretched over 100 miles. It separated West Berlin which was democratic from East Berlin which was communist, with the west side covered in graffiti while the east side remained plain. Over the years, many Germans risked escaping over or under the wall, with most being young people, until it was opened in 1989 when the border between west and east Germany was officially opened, allowing reunification.
