Yeah, it's pretty wild that after 20 years it comes back to a few basic things that continue to roll.

• Email marketing will never die Still the best way to follow up with people
• SMS was the next advancement but it's heavily blocked now by cell phone companies
• Social media is ok but mainly its for reaching masses and expanding your core assets like email
• Article marketing has been around FOREVER there used to be article marketing sites and really hive is just that lol
• Video is also huge and growing

Not much has evolved. There's been small adjustments and tries and tactics but overall it comes down to those fundamentals.
