TV certainly didn't make radio irrelevant, radio is very relevant in situations where you can't look at a screen, or would prefer not to. It's also much lower bandwidth, takes up a lot less space, uses a lot less power on the receiver (even compared to say a modern mobile device) and audio only content is much cheaper to produce. I've heard it argued that podcasts make radio obsolete. That is more plausible.
