Marvel's ABC television series are a set of interconnected American television series created for the broadcast network ABC, based on characters that appear in publications by Marvel Comics. Produced by Marvel Television and ABC Studios, they are set in the Marvel Cinematic Universe (MCU) and acknowledge the continuity of the franchise's films and other television series. When categorizing their wider television slate, Marvel considers the ABC series to be their "Marvel Heroes" series.
The first television series in the MCU was Agents of S.H.I.E.L.D., developed by The Avengers (2012) writer/director Joss Whedon for Marvel Television and ABC. Starring Clark Gregg as Phil Coulson, reprising his role from the films, the series debuted in September 2013 and ran for seven seasons until August 2020. Marvel Studios was involved in Agent Carter, with Hayley Atwell reprising her role of Peggy Carter from the films, which ran for two seasons from January 2015 to March 2016. Inhumans, a project intended as an MCU film that was redeveloped as a series with IMAX Corporation, was released in 2017. A version of the series' first two episodes were released in IMAX theaters before the series' ABC premiere. Inhumans starred Anson Mount and was canceled after a single season.
Agents of S.H.I.E.L.D. debuted to strong ratings for ABC, but these steadily dropped and all three series ultimately became modest ratings performers. Reviews for S.H.I.E.L.D. compared it unfavorably to the MCU films at first, but these improved and the response to Agent Carter was more positive. Inhumans was not well received. Marvel and ABC attempted to develop several more series together, including a spin-off from S.H.I.E.L.D. called Marvel's Most Wanted, a comedy based on the Damage Control comics, and a drama centered on the Eternals. Development on any future series was halted when Marvel Television was folded into Marvel Studios in December 2019, though ABC remained committed to featuring Marvel content and began discussions with Marvel Studios for a new series shortly after.
