As far as advertisers see it, television is still the most effective medium for getting their messages to consumers. 

During the first three quarters of 2013, global advertisers spent more money on television ads than any other media type by far--even despite massive growth in Internet ad spending, according to Nielsen's quarterly report. The report, released on Monday, found that TV ads accounted for 57.6 percent of total ad spending during the period. 

Spending on Internet ads increased by 32.4 percent during the first three quarters of 2013 when compared to the same period a year before--the largest gain by any ad category and an indication that Internet display ads might be a bigger player in the future. Still, Internet ads only accounted for 4.5 percent of overall global ad spending. 

In addition to TV and Internet ads, outdoor ads saw a hike in spending. The percentage of total ad spending on the newspaper, magazine, radio, and cinema categories all dropped during the first three quarters of the year.
