English: commercial publication
Welsh: cyhoeddiad masnachol
Subject: Cyffredinol
English definition: Although any online publication using advertising, banners, product placement etc can be considered commercial, for the purposes of legal deposit, this refers to publications where a direct payment (subscription, micropayment etc) is required for access to read.
Welsh definition: Er y gellir ystyried unrhyw gyhoeddiad ar-lein sy'n defnyddio hysbysebu, baneri, lleoli cynnyrch ac ati yn fasnachol, at ddibenion adneuo cyfreithiol, mae hyn yn cyfeirio at gyhoeddiadau ble gofynnir am dâl uniongyrchol (tanysgrifiad, microdaliad ac ati) am gael mynediad i'w ddarllen.
