About
日本の産業と技術の歴史を、一次資料から読み解くチャンネルです。 有価証券報告書、特許、社史、第三者委員会報告書。 公開されている記録だけを使って、 「なぜその製品は生まれ、なぜ消えたのか」を順に追っていきます。 推測で埋めた話はしません。 確認が取れなかったことは「取れなかった」と言います。 資料室の記録係・クラモトが、届いた箱をひとつずつ開けていきます。 ▼扱っているもの 消えた製品／消えた会社／日本が世界一だった技術／その後に起きたこと ▼参考文献 各動画の概要欄に、使用した資料をすべて記載しています。

Frequently asked questions
How accurate are these YouTube channel analytics?
Subscriber, view, and video counts come from YouTube's public API and refresh regularly. Growth and revenue figures are estimates built from tracked historical data, so they can differ slightly from what a channel owner sees privately in YouTube Studio.
How is a channel's global and country rank calculated?
Rank compares this channel's subscriber count and view count against every other channel Socialcounts.org tracks, both worldwide and within its home country.
How is the revenue estimate calculated?
It's a rough public estimate based on a $0.7–$2.0 CPM (revenue per 1,000 views) applied to view counts — not actual creator earnings, which depend on ad rates, audience geography, and monetization settings YouTube doesn't expose publicly.
Can I check analytics for any YouTube channel, not just my own?
Yes — search any public YouTube channel by name, handle, or channel URL. No login is required to see the basics.
Is this YouTube channel analytics checker free?
Yes. You get 10 free channel and video analytics lookups per rolling hour without an account — logging in, which is also free, removes that limit entirely.
