Hollywood Vault: Film Libraries before Home Video
by Eric HoytHollywood Vault is the story of how the business of film libraries emerged and evolved, spanning the silent era to the sale of feature libraries to television. Eric Hoyt argues that film libraries became valuable not because of the introduction of new technologies but because of the emergence and growth of new markets, and suggests that studying the history of film libraries leads to insights about their role in the contemporary digital marketplace. The history begins in the mid-1910s, when the star system and other developments enabled a market for old films that featured current stars. After the transition to films with sound, the reissue market declined but the studios used their libraries for the production of remakes and other derivatives. The turning point in the history of studio libraries occurred during the mid to late 1940s, when changes in American culture and an industry-wide recession convinced the studios to employ their libraries as profit centers through the use of theatrical reissues. In the 1950s, intermediary distributors used the growing market of television to harness libraries aggressively as foundations for cross-media expansion, a trend that continues today. By the late 1960s, the television marketplace and the exploitation of film libraries became so lucrative that they prompted conglomerates to acquire the studios. The first book to discuss film libraries as an important and often underestimated part of Hollywood history, Hollywood Vault presents a fascinating trajectory that incorporates cultural, legal, and industrial history.

Home Networking Annoyances
by Kathy IvensThe beauty of a home network is that it can make life so easy--what could be better than sharing an Internet connection so that everyone can be online at the same time? With home networking you can move files from one computer to another, share resources, print to a single printer or multiple printers from any computer in the house, and IM the kids when they're holed up in their rooms. And the downside? Anyone who's ever had to troubleshoot a network glitch doesn't need to ask that question. The simple words, "Why can't I print? Why can't I get to the Internet? Why does my computer say 'Access Denied' today, when it worked fine yesterday?" are enough to send the home network administrator running for cover. And the concept of "network security" can keep the soundest sleeper tossing and turning all night. Currently, more than 8 million homes in the US have installed a network of some kind, and within five years, that number is expected to jump to 37 million. This speaks to the availability of easy-to-install home networking products.

This book tackles all the common annoyances associated with running your network--whether it's wired or wireless, or a combination thereof.

Homebrew Game Development and The Extra Lives of Consoles
by Robin WildeThe games industry moves fast, with release schedules flying by in a blur and hardware constantly changing and updating. But outside the official world of licences and publishing deals, hundreds of games every year find a new home on consoles which have since been abandoned by their manufacturers. This is the hobbyist’s playground of homebrew gaming. The first book by freelance journalist and game developer Robin Wilde, Homebrew Game Development and The Extra Lives of Consoles is the first comprehensive history of the unlicensed and unofficial world of homebrew video games. It explores the methods, enthusiasm and motivations behind the developers who are defying technical limitations and turning nostalgia into brand new gaming experiences for retro consoles. Featuring exclusive interviews with developers behind homebrew hits and Kickstarter successes, as well as others working in the industry, the book dives into what makes the homebrew world tick, and explores some of the best, most innovative, and strangest titles gracing long-retired consoles. As well as providing unique insight into obscure titles, Homebrew Game Development and The Extra Lives of Consoles explores the ongoing developments in this cottage industry, which are opening it up to more and more aspiring developers. Homebrew is an exciting new frontier for game development, and this book opens the door both for readers who were already interested but didn’t know where to start, and gamers who never knew this world existed.
Homebrew Gaming and the Beginnings of Vernacular Digitality (Game Histories)
by Melanie SwalwellThe overlooked history of an early appropriation of digital technology: the creation of games though coding and hardware hacking by microcomputer users.From the late 1970s through the mid-1980s, low-end microcomputers offered many users their first taste of computing. A major use of these inexpensive 8-bit machines--including the TRS System 80s and the Sinclair, Atari, Microbee, and Commodore ranges--was the development of homebrew games. Users with often self-taught programming skills devised the graphics, sound, and coding for their self-created games. In this book, Melanie Swalwell offers a history of this era of homebrew game development, arguing that it constitutes a significant instance of the early appropriation of digital computing technology. Drawing on interviews and extensive archival research on homebrew creators in 1980s Australia and New Zealand, Swalwell explores the creation of games on microcomputers as a particular mode of everyday engagement with new technology. She discusses the public discourses surrounding microcomputers and programming by home coders; user practices; the development of game creators' ideas, with the game Donut Dilemma as a case study; the widely practiced art of hardware hacking; and the influence of 8-bit aesthetics and gameplay on the contemporary game industry. With Homebrew Gaming and the Beginnings of Vernacular Digitality, Swalwell reclaims a lost chapter in video game history, connecting it to the rich cultural and media theory around everyday life and to critical perspectives on user-generated content.

Homer Simpson Goes To Washington: American Politics Through Popular Culture
by Joseph J. Foy&“Informative and entertaining . . . convincingly argue[s] that an interest in popular culture can counterbalance the growing tide of political apathy.&” —Publishers Weekly While pundits may accuse popular culture of brainwashing, indoctrinating, distracting, or dumbing down the masses, the fact is that Americans have long turned to entertainment sources to make sense of politics, through television shows such as The Simpsons, The West Wing, The Daily Show, and Chappelle&’s Show and films such as Election, Bulworth, and Wag the Dog. In Homer Simpson Goes to Washington, Joseph J. Foy has assembled a multidisciplinary team of scholars with backgrounds in political science, philosophy, law, cultural studies, and music. Their essays tackle common assumptions about government and explain fundamental concepts such as civil rights, democracy, and ethics—through the lens of drama and comedy.
Homer Simpson Marches on Washington: Dissent through American Popular Culture
by Timothy M. Dale and Joseph J. FoyA volume of enlightening essays on how TV shows, movies, and music can change hearts and minds. Amid all its frenetic humor, the long-running animated hit The Simpsons has often questioned what is culturally acceptable, wading into controversial subjects like gay rights, the war on terror, religion, and animal rights. This subtle form of political analysis is effective in changing opinions and attitudes on a large scale. Homer Simpson Marches on Washington explores the transformative power that enables popular culture to influence political agendas, frame the consciousness of audiences, and create profound shifts in values and ideals. To investigate the full spectrum of popular culture in a democratic society, editors Timothy M. Dale and Joseph J. Foy gather a top-notch team of scholars who use television shows such as Star Trek, The X-Files, All in the Family, The View, The Daily Show, and The Colbert Report, as well as movies and popular music, to investigate contemporary issues in American popular culture.
Homo Ludens
by Johan Huizinga"A happier age than ours once made bold to call our species by the name of Homo Sapiens. In the course of time we have come to realize that we are not so reasonable after all as the Eighteenth Century with its worship of reason and naive optimism, though us; "hence moder fashion inclines to designate our species as Homo Faber: Man the Maker. But though faber may not be quite so dubious as sapiens it is, as a name specific of the human being, even less appropriate, seeing that many animals too are makers. There is a third function, howver, applicable to both human and animal life, and just as important as reasoning and making--namely, playing. it seems to me that next to Homo Faber, and perhaps on the same level as Homo Sapiens, Homo Ludens, Man the Player, deserves a place in our nomenclature."--from the Foreward, by Johan Huizinga
