Ohio law defines a business pursuit as work "engaged in regularly" which "produce[s] an income." Watkins v. Brown, 646 N.E.2d 485, 488 (Ohio App. 1994). CMLP has identified no Ohio cases interpreting this test in the context of online publishing out of the home (or elsewhere). As a general matter, however, Ohio courts have deemed activities to be business pursuits even when profit was not the primary motive and the amount of money earned was small.
Therefore, if you live in Ohio, you may be in danger of losing coverage for your online publishing activities if you make money from your website or blog, such as through advertisements or a tip jar, unless those activities are temporary or sporadic.
Note that specific language in a policy might lead a court to a result different from the overall state trend.
