Arrowverse

The **Arrowverse** is a group of  television programs that take place in a shared universe. It is based on characters that appear in publications by DC Comics. The shared multiverse is like the DC Universe in these comic books. The programs have had crossover stories, settings and characters from other series in the group. The group began with the series *Arrow* in 2012. Over time, it added *The Flash*, *Supergirl*, *Legends of Tomorrow*, *Batwoman* and others.  

## History 
The CW began airing *Arrow* in fall 2012. The program was very successful. This caused the network to make a *The Flash* spin-off the next year. Barry Allen was planned to be in the eighth and ninth episodes of the second season of the series. The twentieth episode of that season was to be used as a backdoor pilot for the new series. After the people in charge saw the first episodes, they decided to order a pilot episode for the series rather than waiting until the end of the season. In early 2015, the CW announced a web-series for *Vixen* to air on the CW Seed. Two months later, The CW said an additional series, ''DC's Legends of Tomorrow'' was to be broadcast in early 2016. On August 12, 2015, Wendy Mericle said their version of John Constantine would follows the same continuity as NBC's *Constantine*. On December 12, 2018, Marc Guggenheim said their version of Barry Allen follows the same continuity as CBS's *The Flash*.
