Input: Today, we expect Apple adverts to be slick and occasionally packed with celebrities. But back in 1987, things were a little different. The company's top executives, including co-founder Steve Wozniak, made a humorous video predicting the firm's meteoric growth rate for the next decade, as well as Macs that project holograms and smart spectacles a little bit like Google Glass. In Apple CEO John Sculley's vision of a future 1997, Mac products are everywhere and 'Apple is in everything, from news to stand-up comedy.' The advert was particularly plucky because it was made just two years after founder Steve Jobs was ousted from the company.Video made in 1987 shows Apple executive's predictions for 1997These include 'Google Glass' and a Mac that projects hologramsExecs also predict Apple would show incredible growth in 1997, when in fact it was on the verge of bankruptcy without Steve Jobs at the helmVideo also shows glimpses of 'Siri' and other iPhone features
