Sure, here's one. At the time (~12 years ago), Groupon was a booming business. This newspaper (and many others) decided to try and get in on the action by creating their own local versions of daily deal sites. That team just focused on the local newspaper's version of daily deal probably employed at least 20 people, including resources from the web team that had to build and maintain a deal site akin to Groupon.
All of that in sum likely had a high price tag, and like Groupon itself, eventually puttered and faded away.
Is it their fault for trying to find a way to increase revenue? I don't know. At the same time they were doing that, the newspaper itself (both print and online), was bloated with advertising, to the point where the website was almost unusable.
