That somehow made me think of the viagra ads as an indicator of a changing of eras.

The viagra ads were a product of a time when the goal was to immediately and directly sell things. Now the era has shifted to one where the goal is to sell your information to people that want to sell you things (or otherwise use that information to further their ends). So instead of spamming you with viagra ads you're spammed with requests to divulge information at every turn you make. Register for this, register for that, give us your email address, let us access your location, let us send you an SMS (aka let us have your phone number), login with your facebook account, talk about yourself, and so much more.

Think I preferred viagra spam.
