However, it's important to note that:
* Television landscape is constantly evolving: New shows premiere all the time, so there might be a show that fits this description that has been released recently.
* Representation can be subtle: While not explicitly featuring a same-sex married couple as the main focus, some CBS shows might have supporting characters who are in same-sex relationships.
* "Original" can be ambiguous: CBS might have aired shows that were originally on other networks that feature same-sex married couples.
To find out if a specific show fits your criteria, it's best to check the show's website, IMDb, or other sources of information.
