Since the invention of modern technologies in the 21st century, pornography has become easily accessible to any individual wishing to view this type of material. Technological advances have helped elevate pornography from the obscure black market to a booming multi-billion dollar industry. Since the 1990s, a computer with an Internet connection can view porn and has been available to almost anyone who can afford it. Of course, there were efforts to suppress pornography during its early years in the United States. This included outright banning of pornography, banning its sale, censorship, and allegations that it is prostitution subject to regulations governing prostitution. However, the United States simply introduced the idea that the seller's intent was demonstrated by the manner in which he presented his case to the jury and the court. This was the determining cause in determining whether something was obscene. Publisher Ralph Ginzburg, convicted under federal obscenity law, sent three sexually explicit publications: a hardcover magazine called Eros that included written advice and visuals such as pictures about love and gender; an issue of a biweekly newsletter whose "Editors' Letter" announced its commitment to making sex an art and preventing it from becoming a science and contained summaries of articles on sex previously published in professional journals and a little book called The Housewife’s Handbook on Selective Promiscuity.” (bc.ed “About” par. 3). When the trial began, prosecutors had reasoned that the provocative material, on its own, might not have passed Roth's obscenity test, since some social significance might have been found. They therefore asserted that the context in which Ginzburg sold his material could be decisive in assessing whether the material was obscene. Finally, there was evidence to prove that Ginzburg intended to sell his material on the black market under the category of pornography. Ginzburg sent his materials with postmarks from towns with provocative names such as Intercourse, Blue Ball, Penn, and Middlesex, New Jersey. This is very vulgar visual material, for example it was not possible to reach readers due to censorship interference from the United States Postal Service. However, the Supreme Court upheld Ginsburg's conviction. Writing for the majority, Justice Brennan withheld information that the defendant in the case had deliberately presented the materials in question as appealing to customers because they could tell that the obscene materials could be aided by the materials being obscene. Brennan wrote: "Where the provider's sole emphasis is on the sexually provocative aspects of its posts, this fact
