If you show it to the young ones today, they would not know what it is. But for those old enough to know what a cassette tape is, today’s a day of commemoration as the cassette celebrates its golden anniversary. Philips, the innovators behind the compact cassette technology, wants to remind us what role these tapes played in our lives. You can check www.cassette50.com for more information and tweet #cassette50 while you’re at it as tribute to those much loved and once revolutionary tapes.
