Best Answer

The technology has changed. Instead of vacuum tubes, transitors were used. This has enabled radios to change from large furniture-like objects to something that fits in a pocket.

Radios predate both the internet and the television. The sorts of things now "broadcast" on these media were once found only on the radio (or in print.)
