And it was good.
Then television came along and supplanted the aural-only medium with amazing visuals AND audio. And everyone said Radio was dead.
It was not.
Not only did Radio survive, but it thrived. AM begot FM which burgeoned in the 1970s. This time, everyone said AM Radio was dead.
It was not.
MTV re-invented how we perceived video in the 1980s. Things became dire and everyone said "Video Killed the Radio Star".
It did not.
In the 1990s, the F.C.C. begot Satellite Radio and the Internet begot Streaming.
By the mid 2000s, broadband begot audio and video streams which comparable to traditional transmission.
And Radio station owners said it was really good (especially all that video capability).
Video Build the Radio Star
Radio and TV have been adversaries since TV came along and tried to crash Radio's party. At first, TV devised programming by luring away famous Radio stars until it evolved enough and realized it didn't have to be just Radio with pictures.
And even though television went its own way, there was always more than a competitive delineation between the two mediums. TV sometimes thought it was better and more compelling because it could offer visuals. Radio was - after all - just sound.
This has changed. Today, video is helping Radio to build brand loyalty, page views, website revenue, and more.
Poke around at your typical radio station website. In case you haven't noticed, Radio is rapidly becoming a multiple personality. The traditional AM and FM over-the-air radio signal is using the power of video in a big way on station websites.
Radio stations are becoming radio and TV stations with on-demand video of artists, video of station events, live streaming events, uploaded videos from listeners, morning show videos featuring favorite stunts, pranks, and bits.
The Internet has give Radio what TV always said it couldn't have: a face to look at.
And now that Radio has harnessed the power of visuals, you can expect nothing less than a constant surge forward to leverage video to its advantage.
