Why are the gospel writers called the "Four Evangelists" in traditional church commentaries / studies, but not in modern Study Bibles?

In viewing and scanning theological literature and commentaries of the past centuries, the four disciples who wrote the Gospels were called "evangelists", the "Four Evangelists". Why were they given this appellation then but not now? Did it have more significance than just "authors" or "disciples then"? Why not the "Four Disciples"? And why do we not see this emphasis or usage of this word to describe them, in very modern Study Bibles and commentaries? Has there been a shift in theology and practice toward "Pastoral Ministry" or "Academic Theology" in recent times? {Additional research in "When was the 'Evangelist' title first applied to the Gospel authors?" *and* "What are the 'gospels' in the Gospels?" }
