Mobile web usage grew 29.4 percent from Q1 to Q2, a period that saw a spike in searches for Barack Obama that was second only to “movies/movie listings,” according to new data from Crisp Wireless. The quarterly report looked at traffic patterns to determine the busiest periods of mobile web usage, a valuable data point for advertisers. Crisp Wireless, which is able to monitor mobile Web traffic through its content platform for media companies and publishers, concluded that traffic driven from carrier decks is falling while mobile search traffic is on the upswing. Nearly 9.5 percent of all mobile web traffic is driven by search engines, of which Google (NSDQ: GOOG) enjoys an 82 percent market share.  (Release).

Some content-related highlights from the Crisp Wireless Index:

-- Local news is viewed most heavily in the mornings while national news is dialed up throughout the day.
-- Sports scores and highlights are often checked during games with peak periods occurring on evenings and weekends.
-- Women typically surf the mobile web at night and early in the week (similar to their online habits) while young girls usually browse later at night, especially on weekends.
-- Entertainment services get the bulk of their traffic at night and on the weekends.
