I work as an in-house designer for a finance firm, which, of course, involves a lot of PowerPoint presentations. One of my bosses thought I’d be interested to see a competitor’s latest presentation he’d gotten hold of, mostly to let me know the work I was doing was much better, bless him.
The presentation wasn’t anything special and didn’t really contain anything terribly cringe-worthy, except for the images (and there were at least two on every slide, in a 26 slide deck).
There was the usual selection of low-resolution ‘stretched-to-fit’ clipart, but the author had also pasted in cartoons, including one of Snoopy, complete with the CartoonStock watermark. But they’d made sure to attribute the cartoons so they couldn’t be accused of copyright infringement - in the footer of every slide, they’d dutifully typed “Source: Google Images.”
