2024 - 47 series started
2014 - 43 series started
2004 - 19 series started
1994 - 4 series started (for reference: Spring 1994 - 18 series started)
Saying the quality declined is also subjective, because the average animation quality has absolutely improved with notable individual exceptions being a big deal. A lot of TV anime used reused key frames, reused backgrounds, just as many still sequences that people bitch about today.
But everyone remembers the standouts, or actually remembers OVAs as "TV series"
