Apple co-founder Steve Wozniak has written an open letter to the FCC

To whom it may concern: I have always loved humor and laughter. As a young engineer I got an impulse to start a Dial-a-Joke in the San Jose/San Francisco area. I was aware of such humor services in other countries, such as Australia. This idea came from my belief in laughter. I could scarcely believe that I was the first person to create such a simple service in my region. Why was I the first? This was 1972 and it was illegal in the U.S. to use your own telephone. It was illegal in the U.S. to use your own answering machine. Hence it also virtually impossible to buy or own such devices. We had a monopoly phone system in our country then. The major expense for a young engineer is the rent of an apartment. The only answering machine I could legally use, by leasing (not purchasing) it from our phone company, the Codaphone 700, was designed for businesses like theaters.
