Visual Basic was first announced on May 20th, 1991, meaning tomorrow is the 20th anniversary. VB6 itself is already 13 years old and many of its spin-offs and clones are still going strong like VBA in excel, Realbasic on the mac, of course VB.NET, and most recently NS Basic that runs on top of javascript (but it's commercial).
