the author states that many of today's ads dont look like ads why does the author think this is a problem?use text evidence

The author thinks that this is a problem because, if ads are being converted into “entertainment” then we won’t know what is ads and what is actual entertainment. The text evidence that supports my answer is “adapting to ever more jaded and fickle viewers marketers have developed ways to integrate ads into entertainment, so it’s hard to tell where the real content end, and the ads begin” (hopefully this answers your question)
