Maybe not 'TV screens' as projection devices but I do agree the network and cable broadcasting model will die off with all the old people who still cling to it. All media will be on demand, with the exception of movies since that 'theater' experience is still something people enjoy and Box Offices are still raking in the cash.
Here's my bold one: Aging.
Another one: Real meat (other than in fancy restaurants).
Finally: A free and open internet (ehhh, I guess it depends on how you define it).
