I've been reading the threads about Google killing off products - to the point where it's become a meme. Lost in this are the number of products killed off by other large tech firms. A shame because sometimes objectivity is lost in the analysis.
Your phrasing got me thinking about some of Google's successes (off the top of my head):
They have old successes in search and gmail. In these cases, they climbed their way to the top. The have google.docs, youtube (oldish) but entering TV/Movies now, android (not that old), Chrome Browser, ChromeOS & their entry into schools, translate, google.storage, maps, that dohickey used to stream video to TV sets (can't remember the name:)...
Google Plus probably deserves a quick death. I just wouldn't underestimate Google by downplaying their successes.
