Microsoft Bob: The Cartoon House That Flopped — and Gave Us Comic Sans, Rover, and Clippy

Microsoft Bob was Microsoft's 1995 attempt to replace the Windows desktop with a cartoon house. It lasted about a year, sold roughly 58,000 copies against expectations of millions, and became one of the company's most famous flops. Its legacy outlived it: Rover the dog, Comic Sans, and Clippy all trace back to Bob.

The short version

Microsoft Bob was Microsoft's 1995 attempt to replace the Windows desktop with a cartoon house. It lasted about a year, sold roughly 58,000 copies against expectations of millions, and became one of the company's most famous flops. Its legacy outlived it: Rover the dog, Comic Sans, and Clippy all trace back to Bob.

What it was

Microsoft Bob was a replacement interface for Windows 3.1 and Windows 95, released March 10, 1995, under the codename "Utopia". It was discontinued in early 1996, about a year after launch.

Instead of the Program Manager desktop, Bob showed a virtual house. The user moved between rooms, and each piece of furniture was an application: pen and paper on the desk opened the word processor, a checkbook opened the finance app, a clock opened the calendar. Cartoon assistants guided the user with speech balloons, led by Rover, a yellow dog. Other guides included a rat, a cat, and a caricature of William Shakespeare.

The project was led by Karen Fries, a Microsoft researcher. The design drew on research by Stanford professors Clifford Nass and Byron Reeves on how people treat computers like people. Melinda French — later Melinda Gates — worked on the product and marketing side as a marketing manager for multimedia products, and later became General Manager of Information Products. She left Microsoft in 1996.

What was inside

Bob shipped with a small suite of built-in applications:

  • Letter Writer — basic word processor
  • Checkbook — financial tracking
  • Household Manager — maintenance lists, household records, vacation planning
  • Financial Guide — advice on life milestones like buying a home
  • GeoSafari — educational geography game
  • Calendar — calendar and to-do list
  • Email — early email client, via MCI Mail
  • Address Book
  • Clock — timers and alarms

Bob could install new applications, but only one add-on was ever released: Microsoft Great Greetings.

Why it failed

  • Sales: about 58,000 copies sold (PC Data), against Microsoft's expectation of millions — the scale of Microsoft Works and Encarta.
  • Price: around $100, a steep ask for something most people could not tell was a tool or a game.
  • Requirements: 8 MB of RAM and 30 MB of disk, heavy for a typical home PC of the time, and slow unless the machine was fast.
  • Reception: reviewers panned the childish look and the endless tutorial speech bubbles that had to be clicked through. PC World ranked it #7 on its list of the 25 worst tech products of all time; CNET called it the worst product of the decade; Time put it on its 50 Worst Inventions list.
  • Timing: Windows 95 launched five months later with a normal desktop, and Bob became redundant overnight.

What it left behind

Bob failed, but three things outlived it:

  • Rover returned in 2001 as the Search Companion in Windows XP.
  • Comic Sans was designed by Microsoft type designer Vincent Connare for Bob — Rover's speech rendered in Times New Roman looked wrong coming from a cartoon dog. The font missed Bob's ship date and debuted in 3D Movie Maker, then Windows 95.
  • Clippy, the Office Assistant in Office 97 through Office 2003, descended directly from Bob's helper concept.
  • Microsoft even hid an encrypted copy of Bob on Windows XP install CDs to take up space and discourage piracy.
