No, TV caused radio to find a new venue, the car rather than the living room, they also found new programming, music and talk, rather than comedy and drama.
The advantage that big media outlets enjoyed through most of the twentieth century, i. e. that to reach a large audience, a large and expensive distribution apparatus is necessary, is gone. Thanks to the internet, an artist can deliver his work, (graphic, written, musical, audiovisual or even interactive) directly to the audience. There is no need for an army of editors, proofreaders, copywriters, typesetters, advertising agents, press operators, delivery people, and the office and administrative staff to support them to get the product to the reader. These roles are now superfluous.
Likewise, the advantage that a large distribution system gives, i. e. a super large audience, is much less necessary to support the artist. Without the big media taking its cut, a more modest audience can support an artist and his/her staff. This allows the artist to take more risks, he can now afford to tailor his message to a smaller but more loyal audience.
What has killed/is killing print, radio, telephone and televison as we know them is the internet, especially mobile internet.
If the people/companies who run these media wish to survive and stay relevant, they will have to adapt to new niches. If they try to cling to their old business model and content streams, either through oppressive intellectual property policies, or monopolistic business practices, they will lose.
