The New York City Subway used to have ads above the seats for some trade school. The general thrust was, technicians always will be in need, because things always will break.

Are ad blockers good or bad? Does it depend for whom? Advertisers and content Web site owners are up in arms over ad-blockers. A report from August 2015 suggested that the industry lost $22 BN in revenue in 2015 due to ad-blockers. Yesterday I visited a news site on my phone - I believe it was Forbes - and it refused to show me the page until I turned off the ad-blocker.
