It used to be that when you read an article in a newspaper you could (mostly) count on some standards of journalism, like fact-checking and research. Not so today.
For every article published, there should be a checklist with assumptions about the article and journalism standards explicitly declared by the author. The emphasis is on an explicit declaration by the author and the publisher. If something (fact checking) is not checked on the standard list, you immediately see it.
Many times you read an article or a blog post that states as a fact something you know to be wrong.

If you walk almost anywhere, you will see plaques celebrating and informing you of interesting people and facts regarding many places (buildings, parks, etc.) There are much more of these than you see on these plaques and many a place where there is no plaque even though it has an interesting history.
An augmented reality app that when pointed at such a place gives you a list of all the interesting things that happened. Famous people who lived there, historical events, etc. You just point it at a building or even a few buildings, or a whole park, and see the list pops up on the screen beside the place you point at. You can them click on any of these to get many more details and the story.
You already have a character that is both famous, and his multiple facets are well known from the media.
Write a fictional novel around that character, or even a series of books with their own world, mixing known facts, background and stories with fictional ones. Just like historical fiction but based on known business leaders.
