Similar early experiments were made in the early 19th century and by 1830 there were several hundred co-operatives.[2] Dr William King made Owen's ideas more workable and practical. He believed in starting small and realized that the working classes would need to set up co-operatives for themselves, so he saw his role as one of instruction. He founded a monthly periodical called The Co-operator,[3] the first edition of which appeared on 1 May 1828. This gave a mixture of co-operative philosophy and practical advice about running a shop using cooperative principles.
