Now we're back at the famous corner of Sunset and Vine, except you look around here today, you say, "What's so famous?"

Over there used to be Glen Wallich's Music City.

That was the social center of Hollywood and the national center of the music business.

And behind it was Tom Breneman's restaurant, a tourist landmark, site of a stone-age talk show called "Breakfast in Hollywood."

But it's what used to be right on this corner that made this corner famous.

This was the Los Angeles headquarters of the National Broadcasting Company, a big complex of radio studios that looked like the starship "Enterprise."

And all they produced was sound.

As Ed Murrow used to say, "I can hear it now."

Groucho: It's me, Groucho Marx.

[Applause] Man: Well, I know where my baton is.

It's right here in the hall.

Woman: Oh, no, McGee, please.

Not on Sunday.

Don't... Man: Bessie, what will we talk about?

Bessie: Well, we can only talk about five minutes.

That's all they want us to talk about.

Ralph: Well, they tore it all down.

The whole city block of NBC Radio disappeared in 1964 and with it, all of the magic...almost.

Actually, some of the machinery of that old magic factory is still here in the basement underneath Home Savings in the club room of the Pacific Pioneer Broadcasters.

And you know, there are other treasure-troves like this all over Los Angeles.

People are saving little bits and pieces of the past for the future.

I know we've seen a lot of "Things That Aren't Here Anymore," but if you've still got your imagination and your memory, they'll always be with us.

Let's see if the thing still works.

[Speaking Spanish] Ralph Story here for KCET.

Good evening, Los Angeles.
