A content provider offers digital goods such as e$-$books and music downloads. The company faces increasing competition from subscription$-$based services that provide unlimited access to similar content. The management is considering shifting from a pay$-$per$-$download model to a subscription$-$based revenue model.

Question:

What is the most significant factor the company should evaluate before making this shift?

The impact on physical goods sales in traditional retail stores.

The scalability of its infrastructure to support unlimited downloads.

The compatibility of its digital goods with multiple device formats.
