uh... I grew up with it too.
49ers dominate in the 90s (2 SB, but it was basically was Cowboys v. 49ers the AFC was irrelevant), then Lakers 2000, 2001, 2002, 2009, 2010, then Warriors, 2015, 2017, 2018. Angels who no one cares about unless you are vacationing in the summer to Disneyland pick up a game on the week trip, they even won in 2002. Then Giants won the world series in 2010, 2012 and 2014. Plus although not the same the whole Barry Bonds/Mark McGuire/Sammy Sosa thing was awesome and Bonds was in SF and McGwire went insane in St Louis he was still rooted for heavily in Oakland -- Sammy Sosa was kinda the villian. It's not like the Bay Area or CA became irrelevant after the 70s/80s era. I include Lakers because that is more heavily rooted for in the Bay Area than like the Kings -- it's prolly 59%/39%/2% Warriors/Lakers/Kings fans.

California has won the NBA Championship 8 times in the last 18 years. Plus have Kevin Durant/Thompson/Green/Curry/(Cousins?) superteam and LeBron in LA. California is winning next yet too.
