National TV ad revenue rose 2.5% in July, thanks largely to gains in sports on cable, according to new figures from research company Standard Media Index.

Cable news and broadcast primetime entertainment also posted increases.

Cable networks registered a 3.7% rise in ad revenue with sports programming up 30% in July. Broadcast ad revenue was up 0.3%

Much of the cable gain came from the Wimbledon tennis tournament, which aired on ESPN and ESPN2 entirely in July. Last year, four days of Wimbledon were played in June. ESPN also aired the X Games in July after they were played in June last year. The network got a bump from a 12% increase in commercial unit prices on its sports talk shows.
