Seth Macfarlane mentions The Orville in an interview about the Peacock series, Ted, and says "the show is not officially ended".
Given all of the Ted series’ castmembers who have appeared on The Orville, is this a sign that we haven’t seen the last of Orville? Any chance of a fourth season?
We...
That would be more like what I was expecting when the show started, and probably why I lost interest in the show. As you noted, if we want a serious space exploration show, we have the ST shows.
Sounds like Season 3 will be the last, though they've left the door open "just in case".

Hulu is no better than paying for cable, since they embed commercials in all their shows. It's actually worse, since at least with cable I can DVR a show and skip the commercials. You cannot skip ads on Hulu.
I signed up for Hulu last year for 99 cents a month. It's not even worth that much.
