If you mean series as in TV series, then there are 4. Adventures of Sonic the Hedgehog (best show ever.), Sonic the Hedgehog (also called Sonic SatAM), Sonic Underground, and Sonic X. The first 3 shows were made by Dic, and Sonic X was made by 4kids.
You need to consider how many fans each of them have... I hate to say it, but Justin Bieber is WAY more popular than Sonic. You don't see Sonic all the time on TV, or see people wearing Sonic shirts everywhere you go. There are a lot of Sonic fans out there, but Justin Bieber definitely has a lot more.
