<p>Let's take a quick sample of full-length non-children's anime that began airing during the current season (Winter 2014) and see which are based on manga.</p>

<ul>
<li><strong>Based on a manga:</strong> D-Frag; Engaged to the Unidentified; Hoozuki no Reitetsu; Inari, Konkon, Koi Iroha; Maken-ki 2; Nisekoi; Nobunagun; Noragami; Saki Zenkoku-hen; Sakura Trick; Seitokai Yakuindomo 2; Silver Spoon 2; Witch Craft Works</li>
<li><strong>Based on a light novel:</strong> Chuunibyou 2; Mahou Sensou; Nourin; ImoCho; Toaru Hikuushi e no Koiuta</li>
<li><strong>Based on something else:</strong> Falcom Gakuen (a video game series); SoniAni (a mascot character)</li>
<li><strong>Not based on anything:</strong> Buddy Complex; Hamatora (simultaneous mixed-media); Nobunaga the Fool; Sekai Seifuku; Space Dandy; Wake Up, Girls!; Wizard Barristers</li>
</ul>

<p>As we can see, roughly half of the series this season are based on a manga, and roughly half are based either on a work in some other medium or are wholly original. </p>

<p>To make a broader point, we can take a look at some data collected by user <a href="http://www.reddit.com/user/homu" rel="noreferrer">/u/homu</a> on Reddit (<a href="http://www.reddit.com/r/anime/comments/1wr94h/tv_anime_adaption_source_by_year/" rel="noreferrer">link</a>).</p>

<p><img src="https://i.sstatic.net/qhB6v.png" alt="TV anime source material year-by-year"></p>

<p>As we can see from this graph, manga has historically been the source for at least a plurality of anime adaptations (though never a majority, at least since 2000). However, other sources are by no means negligible. In particular, the rise of light novels starting circa 2005 appears to have eaten into the market share of manga adaptations, and shows no sign of slowing down as of yet. </p>

<p>All said and done, <strong>yes</strong> - anime that aren't based on manga are pretty common.</p>

Last time I checked, *Silver Spoon 2* was second season of an adaptation of *Silver Spoon* manga.

Even weirder: [Kantai Collection](https://en.wikipedia.org/wiki/Kantai_Collection) is an anime based on free-to-play online social card game.

<p>Has there ever been an anime that was not based on a manga? I notice that most if not all were actually mangas before they were turned into a TV series.</p>

<p>Is it common for an anime to be created without there being a manga first?
Answers are appreciated. :)</p>

@ShinobuOshino That question is a little different in that it's asking about manga that are based on anime, whereas this question is asking about anime that aren't based on manga. There's some overlap between the two categories (since some anime that aren't based on manga will go on to have a manga based on the anime), but I think the questions can legitimately exist separately.

Let's take a quick sample of full-length non-children's anime that began airing during the current season (Winter 2014) and see which are based on manga.

* **Based on a manga:** D-Frag; Engaged to the Unidentified; Hoozuki no Reitetsu; Inari, Konkon, Koi Iroha; Maken-ki 2; Nisekoi; Nobunagun; Noragami; Saki Zenkoku-hen; Sakura Trick; Seitokai Yakuindomo 2; Silver Spoon 2; Witch Craft Works
* **Based on a light novel:** Chuunibyou 2; Mahou Sensou; Nourin; ImoCho; Toaru Hikuushi e no Koiuta
* **Based on something else:** Falcom Gakuen (a video game series); SoniAni (a mascot character)
* **Not based on anything:** Buddy Complex; Hamatora (simultaneous mixed-media); Nobunaga the Fool; Sekai Seifuku; Space Dandy; Wake Up, Girls!; Wizard Barristers

As we can see, roughly half of the series this season are based on a manga, and roughly half are based either on a work in some other medium or are wholly original.
