1971 stereo

1970 - Heard - an ad for a "toll free" number? That's right. It's been around for a year - but something called an "800" toll-free is here. There's a catchy radio commercial for Sheraton hotels that sings, "8-0-0... 3-2-5... 3-5-3-5." It's the first time an 800 number has been given this much attention and listeners are saying, "what kind of number is that?"  ...  More and more FM rock stations can be found. These stations play album rock 'n roll as more younger people are discovering FM stereo radio...
