Cartoon Network had several eras influenced largely by one generations of viewers—millennials. The generation encompasses the main viewing base for either of Cartoon Network’s two programming blocks. Not only that, the generation covers those blocks in each era. Even if older millennials got older, we still watched some cartoons aimed at another part of the generation plus we had the Adult Swim block.

If anything, the end of an era here is in the sense of cable is just fading and streaming is more convenient and big business. Cartoon Network was one the first networks that was really made for 90s-early 2000s broadcasting where marathons were the key to surviving midday hours and late night.

Remaining an actual network was going to be a problem for this particular part of the WB Discovery networks.
