I find Maps and YouTube are still good products
I sometimes throw a YouTube video on the TV for some background noise (or for my cat :-) and if you're not paying attention, the ads can get incredibly long -- not just a few minutes, but 20, 30+ minutes.
Have also woken up to an ad that was hours long.
Not quite sure what the incentive is but maybe it works for some cases, sometimes I wonder if they're scam setups - sitting through a super long ad is a pre filter. Weirder things have been known for Internet scale.
