InFahrenheit 451, how did books become forbidden in the first place?
InFahrenheit 451, books were forbidden as a means for the government to control the thoughts of the public. Excuses such as offensive language and resentment over different levels of intellect, which reportedly made people feel bad, are some of the given reasons as to why books were banned. It was a slow process, and the novel doesn't state the "how" specifically.

According to Beatty’s account, books slowly fell out of favor over the course of several decades when technological advancement proceeded at an ever-quickening pace.
As the speed of life accelerated, people increasingly opted for simplified forms of entertainment, like television.
Fast-paced living & shallow entertainment worked together to erode people’s attention spans.
If people read at all, they read radically abridged books, or else indulged in the mindless pleasures of pulp fiction, comic books, and sex magazines.
Society evolved in a way that privileged happiness above all else.
Books, however, threatened to undermine this ideal of happiness by introducing unnecessary complexity and contradiction into people’s lives.
Books were feared because they brought confusion and discontent.
What began as a matter of social evolution was eventually codified in law, with the government banning books altogether and enforcing the ban through firemen, who started fires rather than putting them out.

Fahrenheit 451 (1966)
Based on one of Bradbury's most famous works, this is the only English-language motion picture ever directed by legendary filmmaker Francois Truffaut. With one significant change -- making the teenage Claire into a slightly older love interest for the protagonist -- Truffaut's movie is richly faithful to Bradbury's allegorical tale of a future society where mindless entertainment (some of it an early version of reality TV)has replaced books, which are now burned for containing dangerous ideas.
