The question is poorly-worded. The word "Media" is the plural of "medium"; and "form of" is superfluous.
So either, "What are your favourite media?" or "What is your favourite medium?"
The Group heading is poor too, to the point of ignorance. If people are still using any particular medium it is not "lost".
My favourite medium is the wireless, sharing my listening between BBC Radio, either Three or Four (mostly music and mostly speech, respectively). Very occasionally I dip into Radio Two but not Radios One, Five or the purely digital channels.
Though I spend rather a lot of time on Similar Worlds this is my only general "social medium". I refuse to use Meta, X, etc.
I love anything to do with radio. Radios have been major part of my entire life. My great grandparents were once owners of one the first broadcast radio stations in New York durning the birth of radio and they would broadcast vaudeville acts on the radio.
So I have radio in bloodstream, I have done commercial radio, amateur radio, and radio restorations.
Shortwave & Longwave Radio are my exact favorites form radio transmissions
Longwave radio uses longer wavelengths (over 1,000 meters) and is typically used for navigation and time signals, while shortwave radio operates on shorter wavelengths (10 to 100 meters) and can reflect off the ionosphere, allowing for long-distance communication. Shortwave is often used for international broadcasting and amateur radio, making it more versatile for global communication.
PS
This is my newest radio restoration I just got started on.
