LONDON, Aug 7 (Reuters) - Britain's top equity index edgedslightly lower on Friday as sharp drops in broadcaster ITV and bookmaker William Hill weighed on the FTSE.
The blue-chip FTSE 100 index was down 0.1 percentat 6,738.85 points by 0836 GMT. It edged 0.1 percent lower onThursday, led by weakness in miners and insurer RSA.
Shares in ITV fell 5.2 percent a day after weak earningsreports from U.S. media left Wall Street bruised and dragged thesector to its worst two-day loss since the financial crisis.
However, some analysts said the read-across might beexaggerated.
"This is a good buying opportunity ... U.S. TV market (is)very different from UK/Europe - channels show a lot moreadvertising (>20 mins per hr) giving consumers a big incentiveto switch off especially given the high cable fees," Liberumanalysts said in a note.
Britain's largest bookmaker William Hill also shed more than5 percent after posting a 12 percent fall in first-halfoperating profit, weighed down by increased machine games dutyand a new tax on bets made online by its UK-based customers.
In a separate statement, the group said it had acquired 29.4percent of NeoGames, an online lottery software and servicesprovider, for $25 million.
"William Hill results highlight the speargun pressurecreated by the additional cost resulting from the Point ofConsumption tax," said Eric Opara, analyst at Edison InvestmentResearch.
"Going forward we would expect smaller players to sufferdisproportionately enabling bigger players with the rightproducts to increase their market share, thus mitigating theimpact of the additional tax cost somewhat."
In other top fallers, Travis Perkins dropped 2.5percent after a target price cut from Panmure.
Among small caps, UK Mail Group plummeted as much as20 percent after warning that its full-year profit would bematerially below market expectations due to additional operatingcosts relating to the transition to its new automated hub inRyton near Coventry.
On the upside, miners recovered from the lows seen onThursday. The FT350 Mining index was up more than 2percent in early deals after falling 1.2 percent in the previoussession.
