(NEXSTAR) – After a 21-year run, the once widely-used video chat app Skype is now officially a memory, as of May 5.

"Rest in peace, Skype," one person wrote on X. "You served us well."

"Listen to that iconic Skype ringer one last time," another urged, adding a clip of the bubbly, slick tone.

Founded in 2003 and headquartered in Luxembourg, Microsoft-owned Skype has been credited with making video calls easy and affordable for millions of people.
