(CNN) -- R.I.P. AIM!
After 20 years of service, the AOL Instant Messenger was taken off line Friday.
The program launched in 1997 and soon earned a coveted spot in pop culture.
It was so popular it made cameo appearances in "You've Got Mail" and "Sex and the City."
But, over the years, users shifted from desktop computers to smartphones and tablets -- and AIM failed to shift with them.
Social media is filled with posts from users with fond memories of the grandfather of instant messaging.
