Dating shows can come out of nowhere. MTV’s “The Challenge” and CBS’s “Survivor” may both be competition series but, more often than not, showmances take up a lot of real estate. The first season of Netflix’s “The Circle” – as well as the rest of the series – devolved into the cast falling in love. Even “The Great British Bake Off” went down the dating show route. No matter how you shake it, viewers can’t escape dating elements of reality shows.
