はじめに

\n 皆さんはネットミームというものをご存知だろうか
\n
\n ネットミームとは基本的に、インターネット上で模倣・改変・拡散が重ねられて広まるネタ的なコンテンツの事を指す。\n 日本で近年大きく話題になったものといえば2024年YouTube流行語大賞にも選ばれた「猫ミーム」が記憶に新しいだろう。\n

\n 近年その影響力はネット上での内輪ネタの域を越えてどんどん大きくなっており、
\n 時に海外では政治的なシーンでネットミームを活用する例も目にするようになった。\n

\n2024年大統領選で大きな話題を呼んだ 「『Kamala brat』ミーム」
\n に反応したカマラ陣営Instagramの投稿\n

\n そんな高い影響力を持つネットミームだが、その大半が爆発的な流行ののち、なぜかすぐに見かけなくなり自然消滅してしまう。
\n そこで私はその自然消滅の部分に目をつけた。

\n 「ネットミームがいつ人々に飽きられてしまうのか」
\n 「いつ流行のピークを迎えるのか」
\n
\n これらがわかれば、目まぐるしく変化するインターネット上の流行りの中で、どれを利用すれば多くの人々のもとに自分のメッセージが届くのか、いつ発信すればより長い間多くの人の記憶に残るのか が予測しやすくなるだろうと私は考える。
\n
\n今回このサイトでは、インターネット上の流行が、どの様にピークを迎えるのか、その後なぜ人々に飽きられてしまうのかを、データの可視化を通して考察し、今後それらの流行を用いる際の手助けになるようなデータをまとめることを目的とする。","pinned":false,"hidden":false,"mode":"md","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"","database":"$undefined"},{"id":184,"value":"## 目次","pinned":false,"hidden":false,"mode":"md","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"","database":"$undefined"},{"id":221,"value":"

\n このミームは、2016年にリリースされた楽曲「恋のHamburg」を使用した料理動画全般のことを指すもので、主にYouTubeShort上で2024年度末から爆発的な流行を見せたミームである。
\n 動画内容は、 『お料理、得意なんです！』 という「恋のHamburg」の歌詞と共に、
\n ”大失敗した料理” の動画を載せるというものが主流。
\n つまり、「自分の失敗した料理」を「お料理、得意なんです！」と言いながら投稿する、いわば自虐的なコンテンツがウケたミームなのである。\n

\n まず、タイトルにもある「オワコン」という単語について解説しようと思う。
\n
\n 「オワコン」とは、通称「終わってしまったコンテンツ」の略で、
\n 旬を過ぎたコンテンツ・顧客が離れてしまったコンテンツのことを指すネットスラングである。最近ではビジネス用語としてモモ陥られることがある様です。

\n まず、YouTube上での検索件数の変化に目をつけた。\n YouTubeでの検索件数がピークに比べ大幅に減っていれば、人々の関心が離れたと言って問題ないだろう。
\n 今回、ミームのキーワードである『お料理得意』と、音源名である『恋するハンバーグ』の２フレーズの検索数の推移を調査した。\n その調査結果が以下のグラフだ。
\n 縦軸は最も検索された際の検索数を100とした際の数値で記録している。\n

\n 視聴者側の関心が薄れていることはわかった。それでは投稿者側はどうだろうか？
\n 視聴者側同様投稿者側もこのコンテンツに飽きて、動画の投稿数が落ちているということも考えられるだろう。もしかしたら動画の投稿数が減少し、それに伴って視聴者も関心が薄れたのかもしれない。
\n
\n そう考え、期間内に投稿された動画の数を日付順で並べた。結果は以下の通りだ。\n

\n 検索件数と同様、 1月2日~4日 三が日のあたりから投稿数が増え始め、1月8-11日ごろがピークになっていることがわかる。
\n しかし、検索件数と異なるのはピークを過ぎても大きく投稿数が減っていないという点だ。多少のブレはあるが、基本的にピーク時の半分以上程度の動画が毎日投稿されている。
\n ピークが起こるタイミングは同じでも、投稿者と視聴者では熱量の下がり方に違いがあるのだろうか。それを確かめるためもう一つ検証を行うことにした。\n

\n 最後の検証として、日毎の平均再生回数で比較することにした。Short動画の仕様のことも考えると、検索件数だけでは視聴者側の関心の度合いを図る指標として不十分だと考えたため、今回再生回数という新たな指標を設けることにした。
