Loser: Spotify. While the streaming platform said it had "the best year ever" in 2015, the majority of its revenue went towards royalty payments.
Loser: Telco firms, which are on the wrong side of the global shift towards messaging. As texting declines, many telcos have launched their own messaging apps, but few customers are using them.
Winners: Candy eaters in Australia, where a new Snickers ad campaign offers discounts based on the mood of Twitter users. However, the campaign website fails to close the loop.
Loser: San Francisco residents, who need to earn almost $150,000 to buy a home - more than in any other major city.
