It was not until 1954 when the FCC authorized the NTSC standard for color television broadcast in the United States. Naturally the availability of what we have today was unthought of and in most cases seemed impossible, but most television sets were capable of providing at least up to four basic channels. However, these channels were only received clearly in larger cities. It was very difficult for television signals to pass through the mountains and rural areas. In order to resolve the problem what is known as cable television was introduced in 1948. The purpose of cable television was to be able to bring existing broadcast signals to rural areas with community antennas placed at high elevations, usually on mountains or on top of tall poles. Since the invention of cable television, it has grown rapidly. By 1960, there were nearly 700 cable systems. In 1971, 2,750 systems were serving almost 6 million homes. Now in the year 1999, the number has risen to more than 65 million. Of course, the invention of cable television was by far if not the only major technological development for television in the early days of television. Today, cable still continues to advance with new developments with satellites. There are over 80 different channels available to cable subscribers ranging from 24 hour music channels, 24 hour movie channels, and 24 hour news channels, and 24 news channels. In addition to being able to have these types of channels, pay television services or better known as premium channels are also associated with the advancement of cable television. These services offer a variety of popular movies, original programming and sports without commercial interruption. Soon after this, interactive television evolved. Interactive TV describes a range in two-way communication services between service providers and end users. Finally, direct broadcast satellites were introduced to further expand cable television. Direct TV and Primestar are just a few companies associated with direct broadcast satellites. It is clearly easy to figure out that television has and will continue to advance. Now that a few various technological advances and developments have been described, they must be tied into what is most important, and that is how viewer perception and societal influence has been changed from television changing over the past 25-50 years. The main change in television has become the command center of our culture

The whole song is about how Courtney has trapped him!
Verse one about how she trapped him on herion, and verse two how she trapped him into having a baby (both against his wishes)

Courtney is a Pisces and astrologically is a dominant sign (She eyes me like a Pisces when I am weak), She gave him a heart shaped box as a present when they first met, and he kept his drugs in it (I've been locked in your heart shaped box for weeks). Magnet tar pit is the actual drug, and "eat your cancer when you trun black", is about how she has made him feel as rotten as she was, ie, the drug addiction.
