Hi Grace. I think the Media lessons were discontinued. I personally found them very interesting, because it was not just studying Chinese, but also learning about some current news and developments along the way.
One problem with going back to the old lessons now is: They contain a link to the news source that they are referring to. I checked about 10 or so and in all cases that link was no longer working unfortunately.
So, should the media content be revived, I suggest that the original text/ video/ speech whatever should be available permanently. Of course, this might pose some copyright issues, but maybe you can finde one news platform willing to cooperate.
