A successful show is often measured by their viewer count. How many views the show gets corresponds to its popularity among its audience. Before dissecting this section we would like to acknowledge the difference in channels in which each show was respectably aired on. The Clone Wars was aired on Cartoon Network, a cable channel while Star Wars Rebels is aired on Disney XD.

“According to the Nielsen, U.S. cable channel coverage estimate (February 2015) there are approximately 80,120,000 homes that receive Disney XD, additionally Cartoon Network (Which was the Channel that broadcast Star Wars The Clone Wars) is received by approximately 96,390,000 homes in the U.S.”

Disclaimers:

For episodes where viewer count was not provided, 2 million is estimated as that is below their lowest episode (ep 10) and consistent with the remainder of the series
Numbers are rounded to the nearest tenth

Keep in mind for SW Rebels that Season One only contained 13 episodes

Note: The x-axis is in terms of episodes

As shown through the graphs, The Clone Wars received and maintained a significantly higher viewer count in comparison to SW Rebels.

Viewership is everything when determining how successful a show is, and is often used as a guidance point to determine on whether or not a show continues onto its next season
- A lack of viewers was never a problem for The Clone Wars
Despite SW Rebels being primarily shown on Disney XD, amount of viewers is still substantial but is still significantly less that The Clone Wars viewership
The Clone Wars gained a large audience, but even more impressive, they maintained it throughout it run as a series
Star Wars Rebels started off strong, however for each episode the viewership dropped until it a little above half a million
