Adobe vadí tweet odkazující na 28 let starý Acrobat Reader pro MS-DOS

Root.cz - 1. Duben 2021 - 23:00
[4 minuty čtení] Před téměř 28 lety, konkrétně 15. června 1993, byl vydán první Adobe Acrobat 1.0 pro MS-DOS. Když dnes na Twitteru na tuto verzi jen odkážete, Adobe proti vám obrátí všechen hněv celého lidstva. Věci, které se seběhly před dvěma týdny, mohou mít spoustu různých příčin. Úvodem ale připomeňme historii a přidejme stručnou charakteristiku společnosti Adobe. Ta vyrostla jako velmi inovativní tvůrce, který dal světu nejmocnější nástroj na grafické práce, program Photoshop. Poté sama v průběhu let tento nástroj inovovala a do svého portfolia postupně přikupovala další a další věci. Třeba Flash, třeba Cool Edit Pro (později nazývaný Adobe Audition), třeba video střižnu od SuperMac Technology (později známou jako Adobe Premiere).
