Newcastle went into the match at St James' Park knowing they were already assured of going up after Nottingham Forest's failure to beat Cardiff City in a 0-0 draw earlier in the evening.
That result meant Newcastle were guaranteed to finish in one of the two automatic promotion places a year after their traumatic relegation from the top flight when local hero Alan Shearer, brought in for the last few desperate games of the season, failed to save them from the drop.
Chris Hughton, who replaced Shearer initially as interim manager before getting the job full time, told Sky Sports afterwards: "It's an incredible feeling, especially to do it here, in front of these supporters.
"We've still got the title to play for but its a real honour to be manager of this football club and bring Premier League football back to these supporters."
The "Toon Army" were already in high spirits before the kickoff, but were silenced when the visitors went ahead through Richard Cresswell after 22 minutes.
West Brom would have been promoted on Monday as well if they had won because of Forest's failure to win but the Baggies will have to wait after drawing 1-1 at Watford.
The draw at the City Ground ended Forest's club-record equalling sequence of 12 successive home league wins.
