Rijksmuseum 荷蘭 阿姆斯特丹國家博物館 將館內的作品以 CC0 的方式讓大家免費下載並應用在商業用途上，約20萬件，介介覺得很有趣的是，當初採用半開放的方式，下載超過 200MB 的 TIF 格式的大型圖檔時，才支付40歐元，免費的部分帶來了龐大曝光量，同時也帶動了圖檔販售的業績 (年收入約18萬歐元)，但博物館支付給圖庫銷售業務人員的薪資，行政雜支發票或信用卡手續費等，高於銷售的業績，於是博物館與基金會決定全部免費，換句話說全部免費竟然還可以多賺錢，這真的是太有趣了!
The Rijksmuseum, a national museum in Amsterdam, Netherlands, has made its collection of works available for free downloading and commercial use under the CC0 license. Approximately 200,000 works are included. Interestingly, when the museum initially adopted a semi-open policy and charged a fee of 40 euros for downloading large TIF format files exceeding 200 MB, it received a massive exposure and boosted sales (annual revenue of approximately 180,000 euros). However, the salaries of sales personnel, administrative expenses, invoices, and credit card fees paid to the museum exceeded the sales revenue, so the museum and the foundation decided to make everything free. In other words, making everything free actually resulted in increased profits, which is really interesting!
