The problem is they cost a lot more, and still had basically zero guarantee of any success. IIRC they were so expensive most single people would have trouble affording them.
I met my wife on eHarmony back when it was relatively new. I had tried one of the non-computerized matching services at some point and it was like 4x what Match or eHarmony cost and it was a pretty poor service.
I probably tried Match in 2000 for the first time? Had a lot of bad first dates on various sites between 2000-2005. Like 50+ people I never went on a second date with?
Back then tech wasn't cool. You could hit it off with someone and then they'd literally get up and leave when they found out your job.
I also tried speed dating, that was popular for a while. It was like a meetup where you talked to different people for 10 minutes each and then at the end checked off on a paper if you were interested in someone you met and if you matched with someone the organizer sent you each other's contact info.
I ended up trying all this cause when I finished college I moved to a new place. I basically knew no one. And at my first job I was like 23 and there was not a single other person under 30 in the division, it was even hard to find people to hang out with as friends. Working as an engineer was very different for me then.
