My understanding over the last half-decade or so is that we have seen a significant shift from traditional print-based products to born digital learning products tied to assessment. This is where we've seen the lion's share of investments from large multinational publishers. Certainly, we represent a specific digital intermediary channel where we've seen approximately $50 million since inception in total cumulative sales.
When this type of product is tied to assessment, students are essentially forced to pay. They don't necessarily have an option to share a book or to use a copy from the library, as an example. In the province of Ontario, we have seen some change in policy that allows the use of these particular products as long as institutions have clear guidelines or policies in place that protect student interests.
