The 10 Longest-Running Anime Series Still Ongoing That You Must Not Fail to Watch [Top 1 Has 7000 Episodes]

Anime has been with us for a long time. It would be over a century old if the Japanese-produced animated film found is any indication. The earliest Japanese animation, Katsudō Shashin, came out between 1907 and 1911 and was discovered in 2005. It is the story of a who in a sailor's outfit and runs only for three seconds. The boy writes, removes his hat, and waves. 

 By the 1970s, classics like Astro Boy and Lupin III came out. It was also around this period when Hayao Miyazaki found his claim to fame. Perhaps it would be logical to think that the anime series from this period have all finished airing, right? 

Hold your horses!

While some anime series ended too soon, some of the anime series that we still enjoy now dates back to even before the time of Miyazaki. Here's a quick look at 10 of the longest-running anime series still ongoing or are in production until now.
