That could apply to a lot of other 'skills' that college teaches, radio or no radio. Journalism courses are still taught at colleges, even though the jobs have dried up. In the 80's, journalism was a viable field. Today, when there are less than 46K journalists in a country that use to have 350K or more (in the 80's, the apex of journalist employment), journalism is just another semi-useless humanities degree.
Some of this is included in the linked GRCC report -- on page 10 it notes that news reporters, journalists, etc. will see a 3% decline in job openings between 2023-2033. I would say the job loss percentage would be more like 30%. In 2023 2000+ local newspapers folded in the US. Not good news for the news industry. The median pay shown in the GRCC report for journalists, of course, is set rather high. I don't know anyone who worked in journalism, personally, who made that much. Maybe some of the big names in TV news make a lot of money, but your average reporter for a local paper (providing they're still in business) doesn't make that much, and many of them never have.
College counsellors often tout a program telling you there will be lots of job opportunities when you graduate, and then you find that you're not only competing with thousands of other graduates in the same field when you get your degree, but either the vagaries of the economy, or tech has reduced the number of open jobs. The 30% of job listings being non-existent, 'ghost jobs' of course doesn't help, either.
And some of the more technical fields like software coding will soon see job losses due to AI. We all know how college degrees have less value in the employment arena than they did in the 1990's, when the value was less than it was in the 1970's.
It's a tough time for radio, and also a tough time for colleges these days. KGRG-1 and KGRG were, in a sense, hit by a double whammy.
Sad to see the plug pulled on KGRG-1 and KGRG, though.
