At first, Bloomberg 1130 WBBR tried to compete with WINS and WCBS with a news format aimed a bit higher. Not as much crime and more financial news. But, as said above, WINS and WCBS had the ratings and longevity. Few New Yorkers saw the need to switch.
So WBBR concentrated on its natural audience, people involved in business and finance. WBBR and the Bloomberg Terminal cross-promote each other for the Wall Street crowd. Traffic reports went from every ten minutes to every 15. Most of the time, WBBR 1130 simply carries the Bloomberg network, now also on 106.1 Boston, 99.1 Washington and 960 San Francisco. There are some local news inserts each hour for the four markets. During those inserts, there's some filler for the Bloomberg channel on Sirius XM. A couple of stations in Toronto and Vancouver even carried Bloomberg for a while, but with Canadian news inserts.
Then last year, Bloomberg decided to give up Total Traffic reports in each city, which included weather and sports updates, too. I've heard that iHeart increased the terms for carrying the service and Bloomberg decided it was too high. (Total Traffic also lost the Sirius XM traffic channels and all the Salem news/talk stations, except for a few morning drive reports.)
Now, Bloomberg has no traffic. It gets pre-recorded weather reports from The Weather Channel and I'm not sure who supplies sports reports on weekends.
