A 22-minute video, posted on YouTube by ComputerHistory, shows interesting footage of Steve Jobs talking about Apple at a presentation in 1980.

FunkySpaceMonkey.com highlighted the video, which shows the late Apple co-founder talking about Apple's growing success, and answering questions from the audience.

In 1980, the year the presentation shown is said to have taken place, Apple launched the Apple III and went public, causing the company's share price to jump from $22 to £29 on the first day of trading.

During the presentation, Jobs describes the beginning of Apple and claims: "When we first started out we didn't know how to spell the word software".

Jobs suggests Apple's growing success was, in part, due to the employees, who he describes as "a collection of the most incredible people on the planet".

Jobs' presentation is light hearted, humorous, and entertaining, and he manages to make the audience laugh frequently, demonstrating his widely recognised ability to captivate an audience.

It has recently been reported that Two and a Half Men star Ashton Kutcher will play Steve Jobs in an upcoming independent film.
