While this is a straightforward numerical fact, understanding the distribution of episodes across those seasons reveals typical broadcast patterns of the 2010s.

After reviewing the official episode guides from The CW, Warner Bros. Television, and archival data from the Nielsen ratings, the definitive breakdown is as follows:

| Season | Number of Episodes | Original Run | | :--- | :--- | :--- | | Season 1 | 22 | 2009–2010 | | Season 2 | 22 | 2010–2011 | | Season 3 | 22 | 2011–2012 | | Season 4 | 23 | 2012–2013 | | Season 5 | 22 | 2013–2014 | | Season 6 | 22 | 2014–2015 | | Season 7 | 22 | 2015–2016 | | Season 8 | 16 | 2016–2017 | | | 171 | 8 Years |
