Who owns a PowerPoint presentation?
The way I see it, it is never “my” PowerPoint presentation…
I create PowerPoint presentations to “give” to my audiences.
I may have created the presentation, but it is not mine.
It belongs to those who choose to experience it.
If I create a PowerPoint presentation at the request of a client, the presentation clearly does not belong to me. It belongs to the client.
The client may choose to give it to an audience. The moment you give it away, it is not yours.
A presentation belongs to its audience.
PS – Copyright lawyers may disagree with me.
