I agree they're not perfectly competitive but they come close (which was my claim). I view them similarly to the soft drinks market, you have moats due to brand such as Coca Cola, but vigorous competition with a heterogeneity of choices for the consumer. If I'm a socialist I can read Jacobin and if I'm very right wing I can read OANN, no matter my perspective I can find print media to suit. TV networks aren't a good comparison to newspapers/print media since they have very high fixed costs and as a result will only cater to markets that represent a sizeable proportion of the populace.
