Oska Oska Software started in 1997 for education and in 1998 evolved to sell interactive desktop characters that Oska calls DeskMates®. A trend which was very popular at the time. Oska succeeded because they promoted DeskMates® through ads in viral animations, often featuring one of the DeskMates® as a character in their animation. Most of their animations are short childish gags, but quite a few are now considered classics from the early days of the Web.
