Multiple Displays From One Source?

I want to be able to display content from my computer to multiple televisions throughout my office, but each television being able to display something different. I know that if i wanted to display the same thing through all televisions I would just need a splitter, but I need the ability to display different content on different screens from one computer. If anyone knows of a way to do this it'll be very helpful, and if there is a way to do it using a mac that will be even better.
