I think the information age has made everything easier. It's hard to even imagine now not being able to know the answer to something. Google has virtually eliminated "I don't know" from my life. You don't have to hope you know someone who knows someone who knows the answer. If static print and television news and entertainment fails to address what you want to know, you can still find it. (I've heard this is a double-edged sword for parents of older children as the technology brings new challenges, but since I don't have older kids, I haven't had to face it yet.)
Internet based technology has also eliminated the gap that used to exist which made it hard for far-off family to feel connected to the young ones. Everyone I know has access to a digital camera if not a digital video camera. Sending pics and emails to our relatives 900 miles away no longer means paying to get film developed and make extra copies to send in the mail.
When I grew up, my parents had 1 set of encyclopedias which were purchased before I was even born. If I couldn't get a ride to the library, all research I did up until about 8th grade came from this one aging encyclopedia set. Our kids will not be restricted to this.
That said, I don't see any difference in the fundamentals of parenting. The physical, mental, and emotional development of young kids seem to require the same thing of parents as always. New parents have trouble getting sleep. Stay at home moms have to make an effort to not turn into recluses. And there always seems to be one more expense I didn't budget for.
