About formats

PWP is a proprietary image format used by Seattle FilmWorks (later renamed PhotoWorks) for their internet-based photo delivery service in the mid-to-late 1990s. When customers mailed film rolls to Seattle FilmWorks for developing, the company offered a Pictures Online service that let users download their scanned photos through a dial-up internet connection. PWP files were the format used for these online downloads, containing JPEG-compressed image data wrapped in a proprietary container with additional metadata for the PhotoWorks viewing software. The format was intentionally tied to Seattle FilmWorks' proprietary desktop viewer application (PhotoMail), which customers needed to install to view and manage their downloaded photos. PWP represented one of the earliest attempts at digital photo delivery — bridging the gap between traditional film processing and the emerging internet, at a time when most consumers had no other way to get digital copies of their photographs. One advantage of the PWP format's historical context is that it preserves scanned film images from a transitional era when few consumers owned digital cameras or scanners, making PWP files potentially the only digital record of photographs from that period. The format's JPEG-based internal structure is another practical consideration: despite the proprietary wrapper, the underlying image data uses standard JPEG compression, and tools like ImageMagick, XnView, and dedicated PWP converters can extract the images for viewing in any modern application.

RB is the native ebook format of the Rocket eBook, one of the first commercially available dedicated e-reading devices, developed by NuvoMedia and released in October 1998. Founded by Martin Eberhard and Marc Tarpenning — who later co-founded Tesla Motors — NuvoMedia designed the Rocket eBook as a handheld device with a reflective LCD screen, capable of storing approximately ten books in its internal memory. The RB format packages HTML-based content along with embedded images, metadata, and a table of contents into a single binary container optimized for the device's limited hardware. Content was purchased and downloaded through NuvoMedia's RocketLibrarian desktop software. A notable advantage of the format was its early support for bookmarking, annotation, dictionary lookups, and adjustable font sizing — features now standard on modern e-readers but revolutionary in the late 1990s. The Rocket eBook demonstrated viable commercial demand for dedicated reading devices, paving the way for subsequent platforms from Sony, Amazon, and others. NuvoMedia was acquired by Gemstar-TV Guide International in 2000, which discontinued the device line in 2003. While RB files are largely a historical curiosity today, they can be converted to modern formats using ebook management tools, and the format remains significant as a pioneering chapter in the evolution of digital reading.
