Photoshop
In arts, computers are used for graphic design and photo editing. Programs like
Photoshop and GIMP are used professionally for this sort of thing. Programs like Adobe Flash can be used to make Cartoons and commercials. There are several programs made for editing video footage, which find extensive use in TV and film entertainment. Computers can also use sound editing programs like Audacity to record things, which are probably used in the music industry.
There are actually a lot of different computer programs made for all kinds of purposes, and I'm sure there are plenty more that I haven't listed.
