2008 was the year dance pop/electro pop became fashionable (although it was kinda emerging since 2006). lady gaga and katy perry also debuted and more and more artists started to use autotune (notably kanye). then in 2009 black eyed peas and guetta popularised electro pop even more. eventually everything on the charts was pretty much EDM in 2010/11 and R&B had died. 2008 also saw flo rida and taylor swift become hugely popular and pitbull and drake in 09. all four are among the biggest acts in the world right now.

facebook started to dominate in 2008 and people started to use twitter in 09, both now being a way of life than simply a social network

the recession happened and unemployment figures escalated

Obama was elected president and the western terrorism paranoia began to calm down

2008 was also the year of the smartphone boom

so yeah in that respect things changed A LOT from 2008. whether it was a good or bad change is subjective. I'm guessing you were young during the 00s so you're obviously gonna be more nostalgic about pre-2008 life because it holds better memories for you. those who were adults in the 2000s probably view the 2000s and 2010s as equally **** and miss 80s or 90s life. it's just natural.
