PageMill was a software program published by Adobe Systems for editing web page HTML in a what-you-see-is-what-you-get (WYSIWYG) fashion. It was one of the first such editors.
Seneca Inc developed the original Pagemill and Sitemill products. During open beta testing, Adobe acquired the company and rebranded the product with their own logo. Adobe released PageMill 1.0 in late 1994. It was considered revolutionary at the time as it was the first HTML editor which was considered user friendly, cited as the "PageMaker of the WWW". This first version, however, was also criticized for lacking items such as a spell-checker and support for creating HTML tables. Adobe acquired Seneca in 1996.
Adobe PageMill 2.0, which was introduced in early 1997, corrected these issues with a package that, according to one review, "adds more features than I have fingers and toes...PageMill with its tables, frames, graphics, and support for form interfaces, makes it easy to lay out a page".
Adobe PageMill 3.0, which was released in early 1999, supported embedded font commands and a site-management feature. It was discontinued in February, 2000 due to the development and promotion of Adobe GoLive. A later patch, still available from Adobe, fixed a problem with FTP upload.
