Object oriented logic with different types for a report

I want to create report mechanism with object oriented design patterns. I want to create a report generator. Reports can be PDF , Wrod, HTML. So I created an interface like this:

interface IReportGenerator{
    Report Generate();
}

class PDFReportGenerator : IReportGenerator{
    public Report Generate(){
        retrun ******;
    }
}

But I have many type of reports. FeaturedProductsReport, MostActiveCustomersReport, BestSellerReporst, etc.

Each type of report is different parameters. So I could aggregate them. How can I do object oriented design these logic?
