How to rephrase this so it isn't a question?

"Other questions that seem to be asked very often are about the boundaries of the television shows. People wonder how far is too far; and compare what is allowed to be said in shows from the 1970’s and shows from today’s time.Finally, people want to know whether the purposes of television shows have mostly remained the time or whether they have differed."

I think you should change the word I used (people) to something more specific to your essay topic at least once, but I'm not sure exactly what you're writing about. Maybe this basic structure could work though?

Other questions that seem to be asked very often are about the boundaries of the television shows. We want to know how far is too far; we want to know what is allowed to be said in shows from the 1970's and shows from today's time and what is not, and if the purpose of a television show remained the same or if it has become different.

The boundaries of the contents of television shows are constantly questioned. Comparing what was allowed in the 1970s, for instance, versus what is allowed today illuminates the changing nature of what is allowed on TV. The purpose of television shows has changed since the invention of TV and what is allowed to air has changed also.

Something like that I think.
