The situation is reminiscent of the newspaper industry, particularly with respect to the significant contribution of a entity to the parent's bottom line. For their entire existence, newspapers have relied on lucrative content, eg, real estate or auto classifieds, cross-subsidizing the rest of the paper. As the internet and smartphone apps came along, the bundle fell apart and migrated into separate services online. New providers captured the lucrative markets and their revenues, removing the ability of newspapers to continue cross-subsidizing the actual news. [1]
