Supergirl's ending did not come as a shock as some of the other Arrowverse shows' endings did, with people involved in the production seeing the writing on the wall. Supergirl's series finale, 'Kara,' was viewed live by under 500 thousand viewers, a far cry from the show's heyday. Supergirl would come to an end with season 6, with the show seeing the worst viewership of its run. The move to the smaller CW led to the ratings plummeting but still holding at a strong 3 million mark for the network. While on CBS, the show managed to maintain very strong numbers, with Deadlinerevealing an average of around 10 million viewers over its first season. Melissa Benoist's Supergirl debuted in 2015, airing its first season on CBS before moving to be with the other Arrowverse shows at The CW. Crisis on Infinite Earths ended up being the final Arrowverse-wide crossover, and shows would begin to get canceled left and right. Following Arrow ending with season 8 in 2020, the Arrowverse would never be the same. The Arrowverse as a whole would also start to struggle with its VFX, which had a very negative impact on the universe's reputation. Over the years, the Arrowverse lost some steam, as the long episode orders, around 20 a season, posed story difficulties as time went on. After that, the Arrowverse grew exponentially, with a slew of new shows expanding the universe and creating yearly crossover events that rivaled the popularity of DC's movies. During Arrow season 2, the show introduced Grant Gustin as Barry Allen for a two-episode arc, which would later turn into the actor leading his own spinoff series, The Flash. The Arrowverse started with Stephen Amell's debut as Oliver Queen in Arrow back in 2012.

The Arrowverse is soon coming to an end after The CW decided to cancel multiple shows for different reasons, effectively putting an end to the DC TV universe.
