LONDON, Aug 7 (Reuters) - Britain's top equity index edged slightly lower on Friday as sharp drops in broadcaster ITV and bookmaker William Hill (Other OTC: WIMHF - news) weighed on the FTSE.

The blue-chip FTSE 100 index was down 0.1 percent at 6,738.85 points by 0836 GMT. It edged 0.1 percent lower on Thursday, led by weakness in miners and insurer RSA.

Shares (Berlin: DI6.BE - news) in ITV fell 5.2 percent a day after weak earnings reports from U.S. media left Wall Street bruised and dragged the sector to its worst two-day loss since the financial crisis.

However, some analysts said the read-across might be exaggerated.

"This is a good buying opportunity ... U.S. TV market (is) very different from UK/Europe - channels show a lot more advertising (>20 mins per hr) giving consumers a big incentive to switch off especially given the high cable fees," Liberum analysts said in a note.

Britain's largest bookmaker William Hill also shed more than 5 percent after posting a 12 percent fall in first-half operating profit, weighed down by increased machine games duty and a new tax on bets made online by its UK-based customers.

In a separate statement, the group said it had acquired 29.4 percent of NeoGames, an online lottery software and services provider, for $25 million.

"William Hill results highlight the speargun pressure created by the additional cost resulting from the Point of Consumption tax," said Eric Opara, analyst at Edison Investment Research.

"Going forward we would expect smaller players to suffer disproportionately enabling bigger players with the right products to increase their market share, thus mitigating the impact of the additional tax cost somewhat."

In other top fallers, Travis Perkins (LSE: TPK.L - news) dropped 2.5 percent after a target price cut from Panmure.

Among small caps, UK Mail Group plummeted as much as 20 percent after warning that its full-year profit would be materially below market expectations due to additional operating costs relating to the transition to its new automated hub in Ryton near Coventry.

On the upside, miners recovered from the lows seen on Thursday. The FT350 Mining index was up more than 2 percent in early deals after falling 1.2 percent in the previous session.
