I know there is a word in Russian that describes all the print media — пресса. Is there any word in Russian that would describe only radio and television?
There's also the noun эфир (lit. ‘ether’), which can be used to refer to both radio and TV (including Internet video streams). В эфире means ‘on air’, в прямом эфире is for ‘live on air’, and you can say something like:
Его жестоко ругали и в прессе, и в эфире
‘He has been harshly criticized in the press as well as on air’
I don't know any word or phrase that specifically describes radio and television. The more general term for all the media is
средства массовой информации (or simply СМИ, pronounsed /smi/ rather than /es-em-i/)
Things that pertain to radio and TV are usually called using something like "радио и телевидение" . E.g.
Музей телевидения и радио
Институт телевидения и радиовещания.
The closest thing that I can think of is broadcast, which would be translated to Russian as
Or, if you want to be more specific about it:
теле- и радиовещание.
Yes, there is such a word. It's телерадиовещание.
