About formats

POTM (PowerPoint Template with Macros) is a macro-enabled template format for Microsoft PowerPoint, introduced with Office 2007 as part of the Office Open XML family. POTM combines the template functionality of POTX — providing reusable slide masters, layouts, themes, and design foundations — with the ability to embed VBA (Visual Basic for Applications) macro code that executes in presentations created from the template. The format is a ZIP archive containing the standard XML parts for slide masters, layouts, and themes, plus a vbaProject.bin stream housing the VBA project. This combination enables organizations to distribute not just visual consistency but also functional automation: every presentation created from a POTM template inherits both the design system and the programmatic capabilities built into it. Common use cases include templates that automatically populate slides with data from corporate systems, enforce content approval workflows, insert standardized disclaimer slides, or provide custom ribbon tabs with organization-specific tools. One advantage is embedded workflow automation — a POTM template can include initialization macros that configure the presentation environment, add custom menu options, and connect to external data sources the moment a new presentation is created from it. The distinct .potm extension serves a security purpose as well, enabling administrators to apply differentiated trust policies for macro-containing templates versus standard POTX files. POTM is supported exclusively in Microsoft PowerPoint desktop editions where VBA execution is available.

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.
