Sonic Boom has had quite a successful run on Cartoon Network, with 2 seasons and over 70 episodes under its belt. The series has won numerous awards including 2017’s Chicago Independent Film Festival award for best animated series. According to the latest press release from Cartoon Network, they might not feel the same about Sonic Boom.
The new press release shows a full list of the 2017-18 lineup for Cartoon Network and Sonic Boom is not listed. It is a possibility that the series is being renewed and there needs to be an official announcement, but it is curious to see Sonic Boom not getting a mention at all.
